Hello everyone. There are moms here whose babies eat very little from the breast in time. My baby sucks for about 5-7 minutes and falls asleep, I can't squeeze her into it anymore. Is she full? I read that at least 15-20 minutes should be enough for the baby to suckle from the breast. The girl is almost 3 months old, the previous two months have been good increases.
