Do newborns form sleep habits?

Not in the way older babies can. Newborn sleep is driven by short cycles and frequent feeds; comfort at bedtime does not create a lasting dependency.

When can we change how the baby falls asleep?

Many families look at gentle changes from around four to six months, if they want to. There is no rule that says you must.

Why do I keep googling this at 3am?

Because 3am is quiet, you are awake, and the fear has nowhere else to go. It is not evidence that something is wrong.

Did I ruin my baby's sleep by rocking them to sleep?

No. In the first months, how a baby falls asleep is comfort, not a habit you created.

The fear that you have 'taught' your baby to need rocking, feeding, or holding comes from advice written for older babies and repeated as if it applied at three weeks. Newborns wake because their sleep cycles are short and their stomachs are small. Rocking a newborn to sleep is responsive care, not a mistake.

Sleep associations can matter later, and there are gentle ways to change them when you and the baby are ready. But nothing you do in the early months closes a door. Babies change every few weeks; so do their nights.

The 3am search for what you did wrong is itself a symptom of how alone that hour is. The answer at 3am is almost always: nothing, and this stretch will pass.

When it is more than this

If you are worried about your baby's breathing, weight, or feeding, ask your midwife, health visitor or doctor. If the nights are breaking you, say that too — sleep deprivation is a health issue for you, not just a phase to endure.
