I never slept as a child. I sleep now but only on rare occasions. New house? Intelligent little girls? Give them a first aid kit and a flashlight. Tell them to make a map of the new house. Ask them to make a list about what they like and don't like about the house. If u are worried about them not getting enough sleep:
If they can't sleep now b/c of the new house, they will probably have some of that energy left to get them through the next day. Little girls are awsome. And as everyone knows, we only get better as we get older. Good luck. U might need it.....
