DD5 and DD4 both do this until I feel like my head is going to explode. My solution is to give them something to do. What works with them is something to learn, so when they were younger it was count to 100 by 1's, 2's,3's,4's ... or spell words now its times tables and division once I get them started on something they go at it until it's learned, gives me time to keep sane. smile
