Is co-sleeping with your baby safe, and how do you do it right?
Kyra Hendrix, certified Gentle Sleep Coach® trained in the Kim West method · updated November 8, 2026
For babies up to 12 months
Safe co sleeping is no problem as long as it happens safely and works for your family. Three forms: a separate crib in your room, a bedside sleeper against your mattress, and sharing a bed. If you share a bed, follow the checklist: firm mattress, not dressed too warmly, no loose blankets or pillows, baby always on their back.
Whether you choose it on purpose or it happens at 3 am out of sheer exhaustion: co-sleeping happens in a great many families. That's why Kyra starts this lesson by saying you're not the only one. Many parents have their baby in bed at some point, whether they planned to or not.
It isn't a mistake
The rule she uses is short: as long as it happens safely and works for your family, co-sleeping is no problem.
That's a different starting point from what you often hear, and it moves the question. Not "is this allowed", but "how do I do this safely".
Three forms
Co-sleeping isn't one thing. There are three ways to have your baby sleep close by, and they differ a lot in what they ask of you.
The safest form is room sharing: your baby sleeps in their own crib, but in your room. Then there's the bedside sleeper attached to your bed, and sharing the same mattress.
The closer, the stricter the conditions.
Safety is the part that weighs most
Kyra is firmer here than anywhere else in the lesson: safety with co-sleeping comes before everything. The risks aren't in the closeness but in the circumstances.
The main points: on their back, a firm mattress without a dip, no loose blankets, pillows or soft toys within reach, and not dressed too warmly. That last one is a real risk, because a baby can't regulate their own temperature well yet. Your body heat comes on top of that.
A firm surface also makes it harder for your baby to roll away. See the safe sleep environment for the rest.
If you want to move on
If at some point you want to go back to a separate crib, that's an ordinary step and not a break. Usually the route goes through the in-between form: first the crib in your room, and only then a room of their own.
If falling asleep only works next to you, that's a separate knot: see falling asleep on you.
