He won't stop crying


My little one is 9 months old and he's always been a great baby. Well this past week he has had an upper respiratory infection, pink eye, and an ear infection, and he's getting 4 teeth at once. He's been ebf since birth. Well all of a sudden he doesn't want the boob, it's hard to ever make him happy. He's starting to feel alot better but he cries so much now. If I put him on the floor he cries. If I pick him up he throws a tantrum all over my lap. Offer the boob, he cries. Offer a bottle, he cries. Idk what to do anymore. Somebody please help! I also must add I just found out Im pregnant. Can he sense it? Does my milk taste different now?
