Your baby falls asleep on your chest in minutes. You lay them down in the crib, and they are awake again almost at once. Plenty of parents ask me whether a baby sleeping on your chest is a habit they should be breaking. I am Nicolas Grimaldi, a pediatric osteopath, and here is why my answer is no.
Why is your baby sleeping on your chest so normal?
Because it is the arrangement your baby is built for. I always start my thinking from the rules of nature. There is no other species with dependent babies that sleeps away from its baby. And the human baby is the most dependent baby that exists in the world, so contact is not a bonus for them. That dependency is my whole starting point. A human newborn arrives needing more from a caregiver's body than any other newborn on the planet. Every species with a baby that dependent sleeps with that baby against the body. When your baby settles the second they land on your chest, they are looking for exactly that.
What does your body give your baby during sleep?
Warmth, skin, a heartbeat, and rhythm. Your warmth regulates your baby's body temperature. Your skin is a cozy place to be. Your heartbeat and all the other rhythms of your body regulate your baby's nervous system, and in my reading their psychology as well. Parents tend to underestimate this part. A chest is not simply a comfortable surface. It is warm, it moves, it breathes, and it beats. Your baby is lying on a set of rhythms, and those rhythms are doing regulating work for hours while your baby sleeps. That is why a crib and your chest are not the same proposition for a newborn. One is still and quiet. The other carries warmth, movement and a heartbeat, which is what your baby's body is organized around.
Is sleeping separately from your baby natural?
Not in my reading. Sleeping apart from your baby is a recent convention. It is new in the history of our species, and it became standard advice inside a few generations. Parents usually raise it with me under the word co-sleeping, and they usually raise it with guilt attached. Here is how I explain it to them. Your baby is born running a basic program. The full version is written now, in these first months, out of what happens to them. Contact is one of the main things doing the writing. So my view is that separation takes something away, and not only comfort. It takes away parts of the program that shape your baby's personality, the bond they form, how they perceive the world, and how they project themselves toward other people. I know that is a strong position. I assume it.
What is your baby already telling you?
That they feel better on you than alone. Your baby cannot put it in words, so they say it by settling on your chest and waking in the crib. I read that as an answer, not as a problem to be managed. Babies are intelligent beings, and I think sometimes they are more intelligent than we are. So if you are lying awake in the middle of the night wondering whether you have built a bad habit, my answer is that you are doing great. Your baby has already told you what works for them. Listen to them, learn to communicate with them, and they will tell you everything.
How does your baby communicate at this age?
Through smell first, with touch alongside it. From a distance a newborn does not see much, and even up close their vision is limited. What carries communication at this stage is smell. Your baby smells you, knows you are there, and answers you. This is the big mistake I watch parents make. They want to communicate through vision, and many are anxious that their baby needs to see them. What your baby needs first is to smell you. Smelling the mother and the milk is part of how a newborn orients itself, and it is tied to survival. Touch works alongside it, and it matters just as much. Now look at what your baby has while sleeping on your chest. Your smell, right there. Your skin against theirs. Both channels open at once, for hours at a time. I show what that exchange looks like with a real baby in the Fulkrum Academy 0 to 6 months program, because it is easier to recognize once you have seen it.
Learn to read your baby with me
This article gives you my reasoning. Reading your baby, and knowing what to do with your hands, is the part that has to be shown. In the Fulkrum Academy 0 to 6 months program I go through how babies communicate at this age, and I teach the holds and the hands-on work I use with them, on video, step by step, in the order I use them. If your baby only settles on you, the next step is learning to read everything else they are telling you. Sign up to the Fulkrum Academy 0 to 6 months program and work through it with me. That is the part an article cannot give you.
