Babies/toddlers/kids are AWESOME. A perk of getting to hang around with them all day is that I get to do tons of fun things I wouldn't likely do otherwise. Here are some of the things I've done or can't wait to do with my son. Have a peek and do some of these with your kid... you'll probably have AT LEAST as much fun as they do, I promise ;)
