Hello everyone! Could anyone tell me if they've ever encountered something like this? The baby is 2 weeks old and constantly asks for the breast, every time I apply it, he spits up afterwards, when he eats in his tummy he has a rumbling sound, since yesterday he hasn't slept all day, only at night he slept for three hours. Since last night I give him Eспумизан, there haven't been any special changes. Maybe I'm overfeeding him?
