Wow, we made the mistake of letting our DD (2.4) eat quite some chocolate yesterday, it being Easter Sunday. We're not food puritans and she has had the occasional taste before but, like I said, she did eat a fair amount over the course of the day. Put her to bed as usual at 7pm and she sang, chatted, made funny noises until 10:45pm! She was physically exhausted but just couldn't switch off. I did know that chocolate is a stimulant, but seeing as it has no effect whatsoever on me, I never considered it would have serious repercussions for my DD. Thing is, she was up at her usual 6:10 am this morning and is, predictably, a grump today. Did anyone else notice a chocolate-induced mania? Just interested...
