DS keeps falling over and banging his head on things which I guess is part of the course for a 9mo old. But the other day, he fell forward onto a piece of spikey coral that another child was holding. I don't want to make a mountain out of a molehill, but I do kind of think that they can't have been watching him. I don't let him go near any pointy things like forks. Poor little thing has little scratches all over his forehead. Any thoughts on whether I should be worried about this? (They have got rid of the coral...)
