Ds used to wear one from the age of 2 till it got too small and he decided he didn't want to wear one. Surprisingly his delicate wrists meant it lasted until age 7.
He's now just 12 and in yr 7 and I think he should be wearing one , I think it'll help him talking about his allergies to his new friends in senior school.
I need to persuade him it's not uncool , what style do your ds' wear ?
