I'm so frustrated with my kids. One is 7 and the other is 5. Every time they see their one year old sister asleep, they HAVE to wake her up! It's driving me insane. I've tried everything from taking things away to canceling plans but this is the one habit they cannot break. It takes me so long to put her to sleep and when I do they sneak into my room and wake her up. She gets cranky. I get mad. And it's just a bad combination. She needs her sleep. I need my rest and need to get things done. How do you teach hour kids to never wake up a baby?
