Hello, my 4 month old has been refusing his bottle for about 2 weeks. He's literally turning his head every time the bottle comes toward him, eventually he will feed as he must be hungry but he doesn't want the bottle. He's also been extremely irritable and not wanting to sleep alone, (crying every time I put him down & wont settle) being quite sick & belly gurgling after milk. Has anyone else experienced this? Could it be the milk I'm using or his maybe just his teeth ??
