hii ,my son used to feed for more than 20 min per day .now he is just feeding for 5-10 min what is the reason

A. Three-month-old babies may start eating less than they did previously. Breastfed babies do get more efficient, so it's normal for your baby to feed in about half the time it took them to feed as a newborn. If you see all the signs that baby's getting enough to eat, it's perfectly normal.
