12 week old ds has been pretty much inconsolable since Tuesday. He had his jabs Tuesday afternoon, could they still be affecting him? When he has fallen asleep, he has woken up screaming. He's messing around when hes feeding and it's taking three times as long as usual. I can't put him down for even a minute without him screaming and getting himself all worked up. Please somebody tell me how to fix him, feeling so guilty that I can't make him feel any better.
