First wheels.

Our daughter is quite the wild one. Always on the go and curious. I think it's time to purchase her first "bike". When my husband and I first spotted one of those "non-pedal" bikes they did put a smile on our faces. I mean, they do look a bit funny . . .
Anyway, I have heard really good things about them and that your child learns how to ride a real bike one day much faster.
So far, so good.
Just still very indecisive whether to go for the wooden or metal one.
Any ideas?
