i really don't know, this may be normal, but this weekend he's started leaning over to get something, sitting, and then just toppled over and banged his head really hard on the carpet. he's been beside himself with upset after both occasions, and i wondered if he should be able to put out his hands to break his fall at this age. Last night he threw up all his supper which he has never done before and i wonder if he really hurt his head. seems ok otherwise. wondering if i should call the doc.
