Hello everyone! The baby is 3 months old and has started taking less breast milk. He sucks for 7-10 minutes with intervals of 2-3 hours, sucking on his fists and seems to chew gum. I shove the breast into his mouth almost forcefully. The mixture doesn't eat. It seems like everything is okay with the child, there was an allergy, it passed, there are no temperatures, stool is moderate, yellow. But he only sleeps for 30 (20) minutes a day, about 3-4 times. His teeth don't seem to be coming out yet. Is this age-related or something wrong with the milk? In my case, the milk might change due to stress
