We took dd for the blood draw (RAST) at 11 months, and it wasn't as bad as I'd expected. I DO think it was worse than if she'd been younger because she's pretty strong and was furious that we had to hold her still. That was the worst part! She didn't even seem to notice the needle stick, she just cried while we had to restrain her and stopped crying (mad crying, not the heartbroken "why are you doing this to me?" cry I'd anticipated) as soon as we were able to free her arms. I don't want to do it again anytime soon, but it went better than I thought it would. She just turned 1 and we go to an allergist for skin testing next week. I wish she were either a bit younger (less mobile and more easily distracted) or a bit older (more able to understand the idea of holding still, etc) but it is what it is. I don't know for sure about the accuracy of the RAST results, but they certainly made sense (well, all of the positives except peanuts, which was a surprise) and she's been noticeably better since we cut the positives out of both of our diets.
