My son is six,and after having a bike for a while, I am letting him ride it to school (on the pavement, very carefully, with a helmet, and he has great manners anyway so no bumping into people!)
Anyway, after seeing Mighty Mites on CBeebies, he has learnt a new skill, to ride standing up, all part of BMX training stuff. (And I will happy to get him a BMX bike in the future, finances/circumstances permitting)
Yesterday, coming out of school my son was upset. He said the lollipop lady had said to him that he shouldn't ride his bike standing up - a skill he had learnt on Cbeebies! When he does this, it's only for thirty seconds or so! We were a few yards up the road when he explained why he was upset, so I suggested we return and politely explain why he was upset, for HIS closure...so we went back and very politely got the lollipop lady's attention. My son said he was upset, I told her that i had given my son permission to ride standing up
