Good day girls. Who has a baby resisting sleep? Mine started resisting:). We're on exclusive breastfeeding, and we have joint sleep at night. He resists during the day mainly: he stretches if in my arms, gets distracted when I give him a breast, becomes active. Although I see that he rubs his eyes and wants to sleep. It wasn't like this before. I calm her down, a couple of times she fell asleep with a pillow then turn her over. If she gets tired, it starts crying, screaming, struggling. I can't understand what's going on ?‍♀️. It was not like this with the older one.
