February 28 - That memory again

Aidan quite regularly impresses me with his memory.  Tonight while he was getting into the tub he says:  "Do you remember a really really long time ago, when I was 2 years old, I fell trying to get into the tub"?  Well I hadn't remembered it myself, but did once he mentioned it and he's right he was either 2 or maybe just 3 when it happened.  By the way, he was fine and I was there with him when it happened, which is probably why I find it even more surprising that he'd remember something like that.
