I have a feeling I'm going to get flamed here, but hell, I'm interested.
I've always been a bit blase about toddler bumps (and I'm talking knocks and small falls, not out of first floor windows or anything), partly because I have first aid training and so do watch DD like a hawk for other signs of poorliness (throwing up, listlessness, unusual tiredness etc) after a collision or fall, and partly because I assume that if every toddler who bumped its head was taken to their local children's (or general) A&E the NHS would collapse.
But, I have to admit, the whole Natasha Richardson thing has brought me up short - particularly as DD had a very accident prone day yesterday, culminating in her falling off a swing with a right old wallop.
So - when do you sit tight and watch, and when do you take them to hospital, and risk being treated like a moron by the triage nurse?
