2yo DS fell badly at soft play today and seemed to hurt his foot, he's now limping. However he doesn't seem to be in pain, he's still walking around and doesn't complain when we move or squeeze his foot so I don't think it's anything too bad. We iced it and gave him a lazy day in front of the telly today. But I've not dealt with this before, any tips on how long it might take and when we should worry?
