DS is 4.5, starts Reception in September. We live 200 yards from our local shop, where they know DS. Today, I thought about letting him go to the shop on his own. We live on a busy road, but there's a wide pavement, and he wouldn't have to cross the road. He's quite sensible.
He seems very young, but he's quite capable of going in to a shop and buying things on his own - he's done that, while I wait outside or in the car, for a year or so now. Is he too young to walk there and back on his own?
