Everyone has those mornings. Your children are grouchy and moving slowly. You keep repeating "hurry up." Sometimes the best cure is beginning again. Stop and say to your children, "Hey, this isn't going too well. Let's start the morning over!" Leave the room, and then come back in with a big smile and say "Good morning!" You may start laughing together, and you'll have a healthier, more productive day.
