My 3 year old DS can't ride a scooter... he can go along on it for a bit but can't steer and loses interest after about 5 minutes. I see all these other tiny kids scooting along on theirs and feel a bit embarrassed that I haven't got him riding his. Has anyone else had this problem? He's got a mini micro scooter - perhaps he needs a bigger one now? He's quite tall for his age. Otherwise developmentallly he's always been fine - sitting, crawling, walking, running etc at the expected ages.
