MY DS made & iced a cup cake at nursery yesterday & I let him eat it on the way home - slapped wrist He also sometime has an ice cream on the way home if it's sunny & he's been extra good, I hope no one sees this either
In fairness, he does eat v.healthily & he's not allowed sweets etc, we offer fruit or yogurt at pudding & he only gets cake at birthday parties.
I think it's all about balance.
