A few things I've learned being a mom of boys:
1. Burps are funny
2. Farts are funnier
3. Dutch ovens are freaking hilarious (check out Urban Dictionary if you're unfamiliar)
4. Any time you can incorporate smelly feet into an art project, you have a winner!
I realize these aren't great footprints (you try painting a screaming squirmy 3 week old and a super duper ticklish 3 year olds feet, ok!)......but they'll do for now!
