Night weaning and nighttime wakings: what we actually know

What the largest French cohort shows

The ELFE study followed 8,696 French infants up to age one. Breastfeeding continued for six months or more is associated there with more frequent nighttime wakings reported by parents at age one, and that association holds up even after adjusting for parents' sleep-related practices.

The same study offers a useful reference point: between 20% and 30% of parents report sleep difficulties in their child at this age. A baby who still wakes at night at age one is far from an exception.

This result needs to be read for what it is: an observed association, not proof. The direction of the relationship isn't established, and the reverse explanation is just as plausible. Parents whose child wakes up a lot may keep breastfeeding longer precisely because it's what gets the child back to sleep.

Does stopping night feeds make a child sleep longer?

None of the studies cited here shows that stopping nighttime feeds makes a child sleep longer. That's a common leap, and it goes beyond what the studies actually support: they compare groups, they don't track what happens when feeds are stopped.

A systematic review of 21 studies and 6,225 infants under one year points to the same caution. Up to six months, exclusively breastfed infants wake more often, but two-thirds of the studies found no difference in sleep duration by feeding method. After six months, more than 65% of the studies found that breastfed infants slept less at night.

A survey of 715 mothers of 6- to 12-month-olds nonetheless found no difference in how often babies woke between breastfeeding and formula: 78.6% of the infants woke at least once a night, and 61.4% had one or more milk feeds at night. Infants who ate more during the day asked for fewer night feeds, but didn't wake any less often.

The authors of the review describe the literature itself as inconsistent. That's probably the most honest thing to take away before deciding anything.

Hunger, habit, or the need to fall back asleep

A waking that ends in a feed or a bottle can have three different reasons: hunger, habit, or a passing phase. They call for different responses. A child who feeds for a long time and drinks a real amount may still have a nutritional need, something to discuss with the doctor who follows them.

A child who feeds for two minutes and falls back asleep probably isn't hungry: the feed has become the gesture that closes the waking. This is the case worth working on, by gradually replacing that gesture with another one, not by cutting it out overnight.

Finally, a child who wakes several times a night at roughly the same hours may simply be going through a regression or a developmental phase, and watching it for a couple of weeks before doing anything at all can save a lot of wasted effort.

If you decide to go ahead, how to do it

Night weaning works better when it's gradual: cutting down the length or amount of a feed over several nights rather than dropping it outright, starting with the one that costs you the most. The decision is yours to make, and it's a legitimate one either way.

Having the other parent handle that particular waking often helps, since the child doesn't expect the same thing from them. And swapping in a different gesture (offering water, physical contact, the same phrase every time) gives the child a new signal that the waking is over.

Count in weeks, not nights. One hard night after three calm ones doesn't mean it isn't working.

A three-week example

A three-week outline can serve as a reference for an eleven-month-old who wakes around 1 a.m. and 4 a.m. and falls back asleep after two minutes of nursing, who is gaining weight normally and eating well during the day. Here, the feed seems to have become the gesture that closes the waking.

In the first week, the other parent handles the 1 a.m. waking, without offering a feed, with physical contact and the same phrase each time; the 4 a.m. feed doesn't change. In the second week, the 4 a.m. feed is shortened, then replaced by the same contact. In the third week, both wakings close with the new gesture, and you watch without changing anything else.

This outline isn't a rule. If the child protests much more than expected, you can stay an extra week at each step. If nothing budges after three weeks, or if the child seems hungry, it's better to talk to the doctor who follows them than to push on.

The same reasoning applies when the gesture isn't a feed: rocking all the way to sleep or lying down next to the child works the same way. A short, identical routine beforehand helps replace those gestures with a signal that doesn't depend on anyone.

When should you see a doctor about night waking with feeds?

A break in the weight curve, a child who seems constantly thirsty or hungry, crying that sounds like pain rather than a call for attention, snoring, or pauses in breathing: these situations call for a doctor, not a change in routine.

Ongoing parental exhaustion is also worth mentioning at a medical visit. It's part of the picture, it can be addressed, and it weighs on a family more heavily than the number of wakings itself.
