Bike Riding

We have been trying to get Logan to ride a bike without training wheels all summer but he just isn't interested. This weekend we took him over to a grassy hill where some of the neighbors have had luck with their kids learning to ride....still no luck! He doesn't want to "get scrapes!" I really can't argue with his theory...there will probably be some scrapes! Ugh...I am going to have to go through this 3 more times AFTER I finally get him taught...this is almost as bad as potty training!
