My almost 6yr old DS has taken up pony riding, for his birthday I’ve had an offer to buy him a riding helmet of his own - currently he borrows one at the stables but obviously that is an additional shared-touch object to think about and he’d probably enjoy the ‘belonging’ of arriving ready to go.
I believe his hat size is currently 6 1/2: 6 7/8 wobbles.
Riding helmets look quite expensive, is there actually any point in buying one at this age (he is obviously still doing very very basic things whilst led, not competitions etc) and how long should I expect one to last before he grows out of it?
