Joshua just had to hold his baby sister, so I helped him put his arms around her and support her and he thought she was pretty neat. Then he looked down at her pudgy little thighs and squeezed one. A little too hard. He thought it was funny. She didn't. She reached up, flinging her arms up in protest and laid a good scratch across his cheek. And suddenly she wasn't so cool anymore! And so begins the love/hate relationship between brother and sister. One minute they'll be beating each other up, the next they'll be protecting each other, fighting tooth and nail anyone who steps on someone's toes!
