What Every New Parent Should Know About Baby Sleep: An Interview with a Pediatric Sleep Consultant

Above all else, I wish parents knew there isn't one "right" way to approach baby sleep. Every baby, parent, and family is different. What works beautifully for your sister or your best friend may not work for you, and that's okay. If what you're doing feels safe, sustainable, and is working for your family, that's what matters.

Two of the biggest myths I hear are about sleep training.

The first is that sleep training increases cortisol and/or damages attachment. That idea largely comes from one small study that had several important limitations, including no control group, no baseline cortisol measurements, and only a three-day follow-up. Cortisol naturally rises anytime we're learning something new or experiencing something challenging. By itself, it isn't evidence of trauma.

When we look at higher-quality research, including randomized controlled trials, we don't see evidence that sleep training harms attachment or emotional development. In fact, we see improvements in parental stress and well-being.

The second myth is that sleep-trained babies stop crying because they've learned no one is coming.

That idea actually comes from observations of children in severely neglectful environments, which is completely different from a loving, responsive home. Babies who learn independent sleep still cry, still seek comfort, and still rely on their parents throughout the day (and night). Attachment is built through thousands of loving interactions over time, not a few difficult bedtimes where your baby is learning to fall asleep with less support.

Everyone's threshold looks a little different.

Some families reach out during the newborn stage because they simply want to build a strong foundation and prevent problems before they start. Others don't ask for help until their toddler is two years old because what they've been doing no longer feels sustainable.

In general, I think it's worth reaching out if sleep is consuming a lot of your time and mental energy, you've tried some free resources without making progress, or you simply have decided what you were doing isn't working anymore.

Sometimes parents don't even realize how much sleep has been affecting their daily life until things start improving.

While it is never too late to make some changes and improve your baby's sleep, it is always easier to take a proactive approach.

The words "cry it out" sound scary. I completely understand why parents have that reaction because no one wants to hear their baby cry.

The first thing I remind parents is that any change can be uncomfortable, and crying is one of the only ways babies communicate that discomfort. Whether you're transitioning out of a swaddle, doing tummy time, taking them out of the bath, weaning the pacifier, or changing sleep habits, there may be some tears.

While methods that include some independent crying have consistently been shown to be both safe and effective, they aren't the right fit for every family.

At The Baby Sleep Haven, I actually use four different approaches depending on the baby's age, temperament, developmental stage, sleep history, and the parents' comfort level.

Some families want a very gradual, hands-on approach that unfolds over several weeks or months. Others prefer to stay in the room while their baby practices new sleep skills. Many choose a middle-ground approach with short timers to allow for independent learning while still checking in, and a few want the quickest path with a more structured plan.

There isn't one best method. My job is to meet families where they are and help them choose an approach they can feel confident following.

Honestly, the transformation in parents is often just as rewarding as the transformation in the baby!

I've had multiple clients tell me they feel like an entirely new person. They finally have the energy to enjoy being a parent instead of just surviving each day.

The words I hear over and over are "confident," "rested," and "peaceful." Parents have more patience, they feel more present with their children, and they're no longer spending every waking moment thinking about how to help their baby sleep better or how tired they are.

Sleep deprivation has a huge impact on mental health, relationships, and overall well-being. Those effects are very real, and I don't think we talk about them enough.

I ask a lot of questions to help them pinpoint what they think and feel.

Especially with first-time parents, I think it can be hard to hear your own intuition over all the advice coming from social media, family, friends, and the internet.

One of the best pieces of advice my own mom gave me after I had my first baby was, "There is no way to be a perfect mom, but there are a lot of ways to be a really good one." I share that with my clients all the time.

I also encourage parents to unfollow or mute accounts that leave them feeling guilty or constantly questioning themselves. Social media can be an amazing resource, but sometimes you need a little space to figure out what you actually believe and what works for your family.

At the end of the day, I want parents to choose the approach that brings them the most peace. For one family, that's safely co-sleeping with risk reduction. For another, it's sleep training because they know everyone sleeps better that way. Neither choice makes someone a better parent.

Absolutely. I'm a big believer that it takes a village.

As a sleep consultant, there are things I can recognize that might be contributing to sleep challenges, like feeding difficulties, reflux, discomfort, possible sensory concerns, or other medical issues. While I can help identify when something seems off, it's outside my scope to diagnose or treat those concerns, so I often encourage families to involve their pediatrician or other healthcare providers.

I'm also very open about my own experience with postpartum anxiety. Even after my baby's sleep improved, I realized there were subtle signs that I was struggling with more than just normal first-time mom worries.

If a parent is feeling persistently anxious, overwhelmed, hopeless, or like they're not enjoying parenthood even after getting more rest, I always encourage them to reach out to their healthcare provider or a mental health professional. Better sleep can make a huge difference, but sometimes parents deserve and need support beyond sleep too.
