Can anyone give advice on which scooter I should get for my 5 year old DS? I'm so confused as there are so many on the market and they vary hugely in price. He is tall for his age but has co-ordination issues due to ASD, e.g he can't pedal bike at all. He has finally and proudly mastered his scooter but it is a toddler one so I want to get him a 'big boy' one, but I want him to be able to use it properly. Any advice would be much appreciated.
