Milk at night
What it's about
Under one year, milk at night may be needed – you decide that with your paediatrician; the app gives no advice on it. Expert bodies give no fixed age from which children no longer need milk at night; it differs from child to child.
Milk and teeth
A review of twelve studies found that bottle-feeding in the first year was not linked to more tooth decay; from 12 months and clearly from 24 months, especially at night, decay was more common. The evidence is considered of low certainty (Alevra 2026). Experts disagree about breastfeeding at night: the American Academy of Pediatric Dentistry (AAPD) advises avoiding on-demand or night-time bottle- and breastfeeding beyond 12 months. The WHO recommends continuing breastfeeding up to two years or beyond and describes breastfeeding on demand, day and night.
If you want to reduce
Sleep consultants often suggest going slowly: reduce the amount bit by bit, then drop one feed after another. For families who want this, the “Less milk at night” goal in the app leads there stage by stage.
If you are worried
Experts recommend contacting your paediatrician or your local out-of-hours medical service if you are worried.
