Baby Sleep in the First Year: What Is Actually Normal

Baby sleep is one of the most searched topics in parenting and also one of the most misunderstood. There is so much pressure to have a baby who sleeps well, sleeps through, and sleeps in a certain way by a certain age, and most of it is not grounded in how babies actually work.

What newborn sleep really looks like

Newborns sleep between 16 and 18 hours a day but in short bursts, rarely more than two to four hours at a stretch. This is biological necessity, not poor sleep habits. Their stomachs are tiny and breast milk is digested in under two hours. Waking frequently is what healthy newborns do.

Safe sleep: what actually matters

The safest sleep environment for a baby under 12 months is on their back, on a flat firm surface, in a room with you, with no loose bedding, pillows, bumpers, or soft toys in the sleep space. The risk of SIDS is highest in the first six months and room sharing during this period reduces the risk significantly.

A firm, flat-surfaced bassinet or crib with a fitted sheet is all that is needed.

White noise and why it works

White noise recreates the ambient sound environment of the womb and helps babies settle and stay asleep by masking household sounds that might otherwise startle them awake. It is one of the most evidence-supported sleep aids available.

Swaddling

Swaddling mimics the contained feeling of the womb and can significantly reduce the startle reflex that wakes babies in light sleep. Use a breathable muslin swaddle for the first weeks, and transition to a zipped swaddle as baby grows and rolling becomes a possibility.

Sleep regressions

Around 4 months, 8 months, and 12 months you may notice that sleep suddenly gets worse. This coincides with developmental leaps, when babies are learning new skills and processing them through lighter sleep. These regressions pass. They are a sign that your baby's brain is working beautifully.

When does it get better?

Most babies start consolidating sleep into longer stretches somewhere between three and six months. Most are capable of sleeping for extended periods by six months, although many still choose not to. By 12 months, most babies sleep better. By 18 months, better still.

You are not failing if your baby wakes at night. You are just in a phase that passes.
