My daughter is 5 weeks and she's hungry all of the time. Can you over feed your baby? She is formula fed. Her belly has gone really swollen and big again the health visitor said it was normal but it's gotten a lot worse. She's also sick after every feed, even when a lot of time has past. And it's not just a little bit she's sick quite a lot. She cry's not long after her last bottle for another one and starts sucking her hands and screaming but I'm scared that I'll over feed her I'm a first time mum someone please help me
