A.S.
I was teaching my 4 yo how. The 8 yo neighbor girl didn't know how and she would hang around and try too. She basically taught herself by gliding on the bike. Watching her helped me teach my dd. Have you seen those glide bike? Its the same idea. Lower bike so her feet are on the ground and walk, not pedal, just glide. A slight down hill helps. This will teach the balance. Once she has the balance then bring in the pedaling that she already knows how to do. One thing that is hard for kids and parents is the fast go the easier it is to balance. Good luck!!!
