What do you do? My friend is visiting with her two boys (7 and 3) and they are playing her up something rotten. Tantrums, biting each other, dreadful whining and so on. Earlier, the younger one was behaving so badly in the soft play centre we were in that his mum nearly burst into tears. I want to do something to help - it's not in my nature to sit by and watch - and she's obviously stressed to the max but why should I do for the best? They really are a pair of little horrors at times.
