There is nothing sweeter or more infectious than the sound of your own child's laugh. It doesn't matter if they're 5 or 5 months, when they get going, you can't help but laugh along.
Sunshine has a knack for making Bug laugh. She thinks it's because of the jokes she's telling him, I'm pretty sure it's the sound of her voice and the fact that she's jumping out from behind a piece of paper. She had him laughing so hard he wasn't breathing. I could see him attempt to take a breath, but she was just too darn funny to concentrate on trivial things like oxygen. Eventually she took a short enough break that he was able to breathe. Right after that when he started laughing he began to hiccup. Poor baby.
Monkey loves to be tickled. Not just a little either, he laughs so hard he cries. When you stop, he'll ask you to do it again. If you don't want to tickle the poor boy, you can bounce him around like crazy on your knee and that is also a riot. Loud, long laughs will come up from his toes and explode in sheer happiness.
Sunshine is at an age now where things aren't funny just because life is fun, she's able to understand things that are said or done that are funny. What is funny is that she can have a very high squeal, but for the most part she has a deep, belly laugh that doesn't sound like it should come out of a little girl. She'll tease my Dad and when he is "surprised" she giggles and covers her mouth with both hands.
I'm pretty sure that the last time I laughed hard (when no children were present) I did not get the reaction that any child will. It is sweet and innocent, honest and pure. It can melt your heart and bring tears of joy and pride to your eyes.
