As per my other thread, we are having to rethink emergency kit after a reaction this week. Until now we have taken it with us when there is a chance he might have food out of the house, but I think he now needs it all the time. He is 7.
Do your children carry their own? what in? what do they do with it while at school? Ours is quite bulky (epipen, puffer plus spacer, bottle of antihistamine and bottle of steroid medication) and I can't really imagine him lugging it around and not forgetting it.
Or do you have several, say one for each parent? We often have a situation where I drop him off at school and DH picks him up, so unless he keeps it with him I don't know how we'd handle that.
