Baby unhappy?

if he is not sleeping during the day maybe he is not sleeping enough and is tired and thats why he is crabby. A baby at that age should be awake for an hour and sleeping for 3 and this should continue all day and night. another issue might be that he has wind. Our daughter was like that one day just would not stop crying and we gave her the infacol drops (they are for wind for babies over a month old) and then she was like a completely opposite child. She was back to her happy self.
