Night Weaning Guide

When are babies ready for night weaning?

Around 6 months, most babies are nutritionally capable of going overnight without eating, according to the American Academy of Pediatrics. But "capable" and "ready" aren't the same thing, and research shows a wide range of normal.

A 2018 study by Pennestri and colleagues in Pediatrics found that at 6 months, 38% of babies still weren't sleeping 6 hours straight. At 12 months, 28% still weren't. Notably, the study found no link between uninterrupted sleep and cognitive or psychomotor development — these babies were developing just fine.

Henderson et al. (2010) found that about 50% of babies slept from midnight to 5 AM by 3 months. By 5 months, roughly half slept an 8-hour stretch. These are averages, and your baby's pace is their own.

Signs your baby might be ready: they're gaining weight well, eating enough during the day, waking briefly but not seeming hungry, and your pediatrician has given the green light.

Night feeds by age

A general guide to how many night feeds are typical at each stage. Every baby is different — these are ranges, not rules.

Breast vs. formula: does it matter?

A very common assumption is that formula-fed babies sleep longer stretches. The research tells a different story. Brown and Harries (2015) found no significant difference in night-waking frequency between breastfed and formula-fed babies. Feeding method didn't predict sleep duration.

That said, breastfed babies may continue night feeds longer for several reasons: breast milk digests faster than formula, nursing provides comfort beyond nutrition, and nursing parents may respond to night wakings differently.

An important distinction: night feeds and night wakings aren't the same thing. Reducing or eliminating feeds doesn't necessarily mean your baby will stop waking. Babies wake between sleep cycles whether or not they're hungry — it's a normal part of how sleep works.

How to night wean

If you and your pediatrician decide it's time, a gradual approach is usually gentlest for everyone. There's no single "right" method — pick what works for your family.

Gradual reduction: For bottle feeds, reduce the amount by 15-30 ml (0.5-1 oz) every few nights until the feed is gone. For nursing, shorten sessions by 1-2 minutes every few nights. When a short feed is all that's left, try settling your baby without offering milk.

Increase daytime calories: Make sure your baby is eating enough during the day. A good feed before bed can help. For older babies on solids, a dinner rich in protein and fat can support longer stretches.

Consistent bedtime routine: Mindell et al. (2015) found a direct link between consistent routines and better sleep outcomes — the more consistent the routine, the better the sleep. A predictable ritual tells your baby a long stretch of sleep is coming.

Partner involvement: If possible, having the non-nursing partner handle night wakings can help break the feed-to-sleep association. The baby learns that night doesn't always mean food.

Is it safe? What the research says

Parents often worry that reducing night feeds or using behavioral sleep strategies might cause lasting harm. Several long-term studies have specifically looked at this question.

Gradisar et al. (2016) studied graduated extinction and gradual bedtime fading in a randomized controlled trial published in Pediatrics. They measured babies' cortisol levels a year after the intervention and found no evidence of elevated stress. Babies in both intervention groups fell asleep faster and woke less often than the control group.

Price et al. (2012) followed up with children five years after a behavioral sleep intervention and found no differences in emotional health, behavior, sleep quality, stress, or the parent-child relationship between intervention and control groups.

Hiscock et al. (2008) found that mothers whose babies received a sleep intervention had significantly lower rates of depression compared to the control group — a meaningful benefit for the whole family.

At the same time, choosing to continue night feeds is also a valid option. If night feeds work for your family and your baby is growing well, there's no developmental reason to stop. The decision is yours.
