Dd has always had a bike with stabilizers (as I didn't know about running bikes then), i and is too scared to try it (despite almost daily cojoling). She is now 5, and still has no confidence with it. She loves scooting on her scooter though. Is she too old for me to get her a second hand running bike to get her balance and co-ordination up to scratch? She totally freaks out if the bike isn't 100% upright, or goes too fast, and she isn't grasping that it is her that is in control of the bike.
