My DS is coming up to 10m and it is becoming a real nightmare to do nappy changes and get him dressed. He refuses to stay still! He'll twist his body into crawling position regardless of what I do to distract / restrain him. I am really finding it sooooop frustrating. Help! Have tried pull up pants but they leak as he has a small bum. Apart from growing a second pair of hands, any tips on keeping him still for the 5 seconds it takes to change his nappy and get his trousers back on?
