Apologies for the thread title - it sounds far worse than it is! (Although it's still frustrating...)
I have 2 sons (age 4.7 and 2.11). The youngest is SO destructive. He regularly tears pages from books, knocks over towers and smashes lego creations lovingly built by his creative older brother, throws things, breaks things, snaps crayons. If it can be destroyed, DS2 will find a way to do it.
He has quite a short attention span and if he's left to his own devices for a split second he will seek to break or destroy something. Some things don't worry me too much, but when his emotional big brother gets so upset when something he's made just gets smashed up for no apparent reason, it's so frustrating.
What can I do?
