My baby is 4 months old. Just last week he started to cry when he is getting fed. He would cry we thought he must be hungry then when we gave him the bottle he drank about 20mls then started to cry, pushing the bottle away. His milk intake is half of what he usually does. I spoke to HV they think it must be due to teething. Then when we at the doctors the next day, the doc had a look of his gum said it didn't look inflamed. I'm really puzzled now what's wrong with him. He is my only child so I'm not sure that's normal for a baby when his teething, giving him reduced appetite and cry when he is getting fed ect.
