Hello, Good day! As your kids ❤️ wanted to ask. I went to school, from about 8:00 to 2:00 pm. The baby is on breast milk, in the morning somewhere around 7:30 I feed him, at 11 he drinks formula maximum 100 ml, I come and he doesn't take the breast. Like this for a week already. I give him breast but he doesn't take it, he gets upset, cries, pushes away. As soon as he falls asleep, he takes it. Or should there be a sleepy one, or only rocking? Why so? What can I do? It used to be like that??? Afraid of refusing
