I apologise now as this will be long. Ds will be 3 in a couple of months. We were thinking of getting a balance bike for his birthday as a) we hope he'd like it & b) we think it might help to develop his physical skills which have always lagged behind his speech/imagination.
Went to look at some today only to be told by shop assistant it was a waste to buy one given his age & he'd be much better going for a bike with stabilisers. He said given he'd not got much experience of ride-ons, a balance bike would be more hinderance than help because the wheels would be too thin & he would likely just fall off.
The fact ds can't pedal yet apparently doesn't matter because he's 'got to learn' & he claims its more important for him to learn how to pedal while fully supported than to learn how to balance. How if he went for a BB then he'd just be lazy as he wouldnt know how to pedal a proper bike & would just push it along & it would take even longer than learning with stabilisers.
He then got me to try ds on a 12" bike, his feet wouldn't even touch the ground & it was so heavy there's no way he's ready for a proper bike yet.
I was quite taken aback with his attitude, esp since i thought most folks think balance bikes are a great idea & can't help thinking he is spouting a load of bollocks rubbish & 
But now am doubting myself - is he right? Is it pointless to get one for a 3 year old?
