We've just got back from A&E and there are a few things that bother me about my 9 month old. He's started to pull a face and shake which he has done a couple of times before but when we got home he did it about five times in quick succession. Which in itself was a bit of a worry and he has bruises on his shins about the size of a finger print which the doctors put down to him cruising but he's been cruising for about a month and this is the first time I've seen bruising. Are these things I should be worried about or am I over worrying?
