One of my favorite memories of my kids when they were little is when my daughter was two and my son was about 8 months old. She jumped, and for some reason he just started giggling. So she did it again, and he started laughing hysterically. This went on for about five minutes, her jumping, him laughing, and her having so much fun making her brother laugh. Before he was born, I was worried about jealousy and sibling rivalry, but this was a moment where I realized that maybe they weren't going to grow up and hate each other after all. :-)
