Baby 5 months sleeping n not eating ?

At 5months, if he's feeding 3hrly during the day, he may not need night time feeds anymore? Is he still having lots of wet nappies each day? If yes, then there's nothing to worry about. If no, then you need to get a 2nd opinion asap! You're the mother and you know your baby better than anyone - if you're not satisfied with your current doctor's advice, definatley go to someone else. Your doctor isn't with your baby all day long - you are, you know him better than anyone. If he's not acting like his normal self and you're concerned about his health - take him to a doctor, or emergency.
