Hello girls. Can you tell me why and what to do? The baby is one month old, wants to eat, I give him breast milk, he sucks a couple of times and throws it up, cries. Again, I give him and the same situation. He sleeps for five minutes. I don't have any strength left. It's sad for her, and for me too, like a zombie, without sleep and rest.
