my 10 month old had an accident the other day, she fell out her high chair, i put her in in the morning quickly while i went to grab her bottle, i forgot to strap her in. i know im a terrible mum i feel awful, anyway she fell out and landed on her face, it was a hard floor and she has a big bruise on her forhead, she has been fine but has developed a cold and been a bit moany, but i dont know if thats her cold doing that, should i be worried????
