Many parents worry that sleep training might harm their baby, damage attachment, or cause long term emotional problems. Questions about cry it out, crying, and sleep training are some of the most common concerns I hear from families. If you are worried that sleep training might harm your baby or affect your relationship, you are not alone.
I am a sleep consultant who works with families with babies, toddlers, and preschoolers on sleep training, night wakings, short naps, bedtime struggles, and sleep schedules. Many of the families I work with feel torn. They are exhausted and need better sleep, but they are worried about whether sleep training is the right choice for their child.
If you spend a few minutes on Instagram or parenting Facebook groups, you will quickly see that sleep training is a very emotional and sometimes controversial topic. There are a lot of strong opinions, and it can be very confusing for parents who are just trying to make the best decision for their family.
So let me say this clearly right from the start. Parents who choose to sleep train are not harming their child. They are not selfish, and they are not bad parents. They are making a thoughtful decision about sleep, just like parents who choose not to sleep train are making a thoughtful decision.
Sleep training is not for every family, and that is okay. But for families who are dealing with frequent night wakings, bedtime battles, short naps, and exhaustion, sleep training can be a very helpful and very reasonable option. And it does not harm your child.
If you are not sure whether you are ready for sleep training, you can read more about that here.
Let’s talk about the most common fears, questions, and myths about sleep training.
In this article, I'm going to cover:
Will Sleep Training Harm My Baby?
This is usually the biggest question parents have, so let’s start here.
Based on the current research we have, sleep training, including cry it out methods, has not been shown to have negative effects on a child’s behavior, development, attachment, or the parent child relationship. Researchers have compared children who were sleep trained with children who were not, and they found no differences in emotional health, behavior, attachment, or parent child relationships months and even years later.
In other words, choosing to sleep train or choosing not to sleep train does not determine your child’s long term emotional health or your relationship with your child.
What does have a very real impact on both children and parents is chronic sleep deprivation. When babies, toddlers, and parents are not sleeping well, it affects mood, behavior, learning, and overall well being. Sleep is important for your child, and it is important for you too.
You may come across articles or social media posts that claim sleep training is harmful. Many of these claims are based on studies that do not actually reflect real life sleep training situations, or studies that are not even done with human babies. For example, one study often mentioned online involved baby rats being separated from their mothers, deprived of food, and left in cold conditions. That is not what sleep training is, and it is not an accurate comparison to a baby learning to fall asleep in a safe crib with responsive parents.
It is not easy to hear your baby cry. No one enjoys that part of sleep training. But based on the research we have and what I see working with families, you are not causing immediate or long term harm to your child by teaching them how to sleep.
Is Cry It Out My Only Option?
No. Cry it out is just one sleep training method, and it is not the right fit for every family.
There are several different sleep training methods, and they mainly differ in how involved you are during the process. Some parents prefer to stay in the room while their baby or toddler is learning new sleep skills. Some parents prefer to check in at certain intervals. Other families find that giving their child more space leads to less frustration and faster progress. There is not one single method that works for every child or every parent.
What many parents are surprised to learn is that the sleep training method is only one part of the sleep puzzle. In fact, when I work with families, we often spend most of our time talking about everything else that affects sleep before we even choose a method. We look at sleep schedules, naps, bedtime, night wakings, sleep environment, and sleep habits. When all of those pieces are in place, sleep training is usually much smoother and involves less crying.
The goal is not to pick the “perfect” method. The goal is to pick a method that you can be consistent with and that feels manageable for you, because consistency is what helps sleep training work.
What If Sleep Training Didn’t Work When I Tried Before?
If you have tried cry it out, checks, or another sleep training method and it felt like your child just cried for hours, you are not alone. I hear this from many families before we work together.
When sleep training does not seem to work, it is usually not because your child is the exception or because sleep training does not work for them. Most of the time, it is because other pieces of the sleep puzzle were not in place yet.
Sleep training is not just about the method. Sleep schedules, naps, bedtime timing, night wakings, sleep environment, and sleep habits all play a big role in whether sleep training works and how much crying is involved.
Sleep timing is one of the most important pieces. If your child is going to bed too early, too late, or at the wrong time for their body, sleep training can be much harder. You can read more about sleep timing and why it matters here.
When I work with families, we go through a full checklist before we start sleep training. We make sure your child’s schedule, naps, bedtime, night wakings, and sleep environment are all set up in a way that supports sleep. This usually means less crying, faster progress, and a much more manageable experience for everyone.
If you have tried sleep training before and it did not work, it does not necessarily mean it will not work. It may just mean we need to adjust the plan and set things up differently so your child is truly ready.
Is There a No Cry Sleep Training Method?
Not really. Those programs that “guarantee” no crying are usually more about a marketing ploy This is a question I get all the time. Many parents come to me hoping for a way to teach their baby or toddler to sleep without any crying at all.
The truth is that when you are making a big change to how your child falls asleep, there are usually some feelings involved. Your baby or toddler may protest the change, and crying is how babies communicate. Crying does not automatically mean something is wrong. It often means your child is frustrated, tired, or adjusting to something new.
Sleep training methods can be very supportive and responsive, and they can involve different levels of parental involvement. Some families choose to stay in the room. Some families do frequent check ins. Some families gradually reduce how much help they give at bedtime and during night wakings. These approaches can help reduce crying, but they usually cannot eliminate crying completely.
Instead of focusing on a “no cry” promise, I like to focus on setting your child up in a way that minimizes crying. When sleep timing, naps, bedtime, and the sleep environment are all working together, most children cry much less and learn new sleep skills much faster.
The goal is not zero tears. The goal is better sleep for your child and for you, in a way that feels supportive and manageable for your family.
Will Sleep Training Harm My Baby’s Attachment?
In addition to being a sleep consultant, I am also trained in infant and early childhood development, and my work is heavily influenced by attachment theory. I spend a lot of time helping caregivers strengthen their bond with their children, especially when there has been stress or disruption in the relationship.
Because of that background, I do not worry that giving your baby the space to fall asleep independently will harm your relationship. I do not worry that your baby will feel abandoned because you are changing how you respond at bedtime or during night wakings.
Your child knows you are there for them. Your baby feels safe, loved, and cared for by you. A secure attachment is not built or broken in a few nights. Attachment is built over months and years through feeding, playing, talking, comforting, setting limits, and showing up for your child again and again.
Changing how you respond at bedtime or during night wakings does not erase a strong relationship. Your relationship with your child is much bigger and stronger than a few nights of learning a new sleep skill.
Sleep training is about how your child falls asleep. Attachment is built in the thousands of interactions you have with your child during the day and over the course of their childhood.
Is Sleep Training Selfish?
Many parents worry that wanting their baby to sleep through the night is selfish. They tell themselves, “My baby needs me. I can be tired. It’s okay.”
But your baby does not just need you at night. Your baby needs a well rested, emotionally available, patient caregiver during the day. And that is very hard to do when you are completely exhausted from frequent night wakings and broken sleep.
Sleep is a basic need for your child, and it is a basic need for you too. When everyone in the family is sleeping better, parents are more patient, more present, and more able to enjoy their time with their child.
Right now, your baby may need a lot of help to fall asleep and go back to sleep during the night. This is often because of sleep associations, which means your child has learned to fall asleep in a certain way and needs those same conditions to fall back asleep. When those sleep associations rely on a parent being there, it can make it very hard for a child to sleep independently and stay asleep.
Teaching your baby or toddler to sleep independently is not selfish. You are teaching a skill that will help them sleep better, and you are also taking care of yourself so you can be the parent you want to be during the day.
There will still be plenty of time for cuddles, snuggles, and connection during the day. Night time is for sleep, and well rested families function better.
Taking care of your sleep is not selfish. It is part of taking care of your family.
Why Is Hearing My Baby Cry So Hard?
Hearing your baby cry is never enjoyable, but for some parents, it feels almost unbearable. Everyone’s situation is different, and I never want to make assumptions. But if listening to your baby cry feels impossible, it can be helpful to gently think about why that might be.
Our own experiences influence how we parent and the feelings that come up for us. This can include our own childhood and relationships when we were young, as well as what we may have already experienced with our own child.
Maybe your baby had a NICU stay. Maybe the first few months included hours of crying and a colic diagnosis. Even if that stage has passed, hearing your baby cry now can bring you right back to those stressful moments. After going through something like that, hearing your baby cry can feel overwhelming.
It is also possible that your own childhood was difficult. As parents, our children can sometimes push buttons that have been quiet for years. Hearing your baby cry, or your toddler become very upset, can bring up big feelings because of our own early experiences.
Being aware of these triggers and feelings can be the first step in understanding why sleep training and crying may feel especially hard for you. What you do with that information is completely up to you. You can wait until you feel more ready, or you can talk it out with someone you trust.
You may be able to separate your own process from what your baby is going through. Talk with a partner, a friend, or a therapist. You can also share your hesitations with me. While I am not functioning as your therapist in this role, I can help support you through the sleep training process and talk through what feels hard about it.
And if it simply feels impossible right now, that is okay too. Be gentle with yourself and give yourself time. If now is not the time to sleep train, you can still make other changes that may help your little one sleep better, like adjusting sleep timing, bedtime routines, and sleep habits.
What If My Baby Cries for Hours?
This is one of the biggest fears parents have about sleep training. In many cases, the fear and anticipation are actually worse than the first few nights.
I am not going to tell you it is fun to hear your baby cry. It is not. But when we set your child up for success with the right sleep schedule, bedtime, sleep environment, and a clear plan, most children cry much less than parents expect, and for a shorter amount of time than when parents have tried on their own without a full plan in place.
That said, if you truly do not think you can follow through with the process, then it is okay to wait. Sleep training requires consistency. Starting and stopping, or changing the plan night to night, can be confusing for your baby or toddler and can make the process take longer.
If you are not ready to fully sleep train yet, there are still things you can work on. You can start by adjusting sleep timing, setting up the sleep environment, creating a consistent bedtime routine, and slowly decreasing sleep associations. These changes alone can often improve sleep, even before any formal sleep training begins.
If you have worries and feel like you need support through the process, this is where I can help. We can talk through your hesitations and make a clear plan so you feel more confident and more prepared going into it. You do not have to figure this out alone.
The Bottom Line About Sleep Training
If you are considering sleep training your baby or toddler, it is very normal to have worries and hesitations about the process. Most parents do. Sleep training usually involves some tears, but you are not causing any immediate or long term harm to your child or your relationship with your child.
Careful planning, choosing a sleep training method you feel comfortable with, and making sure your child’s sleep schedule, naps, bedtime, and sleep environment are set up well can make a big difference in how the process goes. Sleep training is not just about the method. It is about setting your child up for success and being consistent.
Crying and sleep training can also bring up big feelings for parents. It is worth thinking about your own triggers, your past experiences, and what kind of support you might need during the process.
You do not have to figure this out alone. The support of a sleep consultant can make this process much more manageable. We can talk through your hesitations, make a clear plan for your child’s sleep, and problem solve together along the way so you feel confident and supported.
