Girls, hi! I'm planning to finish breastfeeding by the year, tell me your experience We have already replaced the first morning feeding with porridge and today we tried something like "sleepy" for the night for the first time Breast milk is being replaced by formula or complementary food (a full meal intake), how does this happen? As far as I know, first you need to remove chaotic daytime feedings, and then only nighttime ones. And how to avoid lactose intolerance in the absence of daytime feedings, adjust it until relief?
