my dd's early learning centre trike got nicked - debating whether to replace with the same again, or get a scooter instead. she seems quite keen on other kids' ones and it would take up much less space. what age can toddlers scoot along on them? and if not, will i get enough use of the trike to be worth replacing? i do find it useful as dd is a bit of a buggy refusenik unless sleepy.
