My 13 year old DS managed to break his arm a couple of weeks ago and is in a full arm cast. We're off on holiday to the coast tomorrow (with other kids), and I'm wondering whether any wise MNers have any useful top tips? Luckily he's in no pain and is ever so cheerful about the whole situation, but I'm gutted for him, as normally when we go to the beach (which is very rarely), all he wants to do is spend hours in the sea. We've got a limb cover which will protect the cast from a bit of splashing, but the consultant has said it can only be worn for 20 minutes at a time because of condensation. I'd resigned myself to him just playing around on the beach, but the nurse then said we've got to be really careful not to get any sand in the cast
. So - any bright ideas of how we can protect the cast and still make sure he has fun? Or any other general 'kid in a cast' tips?
