Third time is a charm?

I took Parker to ride his bike without training wheels today and he did great. He went several feet to several yards on his own multiple times. He was pretty nervous, but never got too frustrated and really seemed proud of himself about it all. I told him I thought he would "get it" on his third try. He suggested his fifth try. When he does get it, we're going to get him a new bike (his is too small already) and I may even get one too with a trailer for the girls.
