Both Dad and Colleen dived for him. He only tripped at the third or second step from the bottom, but they managed to catch him, and came out with more bruises and bumps then if Chris had just fallen. And we'd all do it again. And have. Because there are a lot of kids in this family, and stairs are tricky when your feet are growing. Heck, Chris caught Oliver when he started to fall down the stairs not too long ago!
