Few things attract more conflicting advice than baby sleep, and most of the pressure comes from comparing newborns to a standard that does not really exist. Early sleep is broken by design, and understanding why takes a surprising amount of the sting out of the nights.
Newborns have small stomachs, short sleep cycles and a strong biological pull to stay close. Frequent waking keeps them fed and is thought to be protective. It is exhausting, and it is also exactly what a healthy newborn does. This is a developmental stage, not a problem with your baby, and certainly not a problem with you.
Responsive settling simply means responding to your baby's cues rather than the clock. Feed, hold, rock, sway, offer closeness. Contact naps count as sleep. In the early weeks none of this builds bad habits. Comfort is a genuine need at this age, and meeting it reliably builds the security from which independence later grows.
You are not training a small machine. You are getting to know a person.
As the weeks pass you can begin, very gently, to help day and night feel different. Daylight and a little activity in the daytime, dim and calm in the evening, and a short, repeatable wind-down all give a small body helpful cues. None of this needs to be rigid, and it works with your baby's biology rather than against it.
If sleep, or the lack of it, is affecting your wellbeing, or if your baby seems persistently unsettled or uncomfortable, it is worth a conversation with your health visitor or GP. Support exists, and wanting some does not mean anything is wrong with how you are parenting.
