My baby boy turned 3. Has it seriously been three years already? We had a big party with a Yo Gabba Gabba theme. I love Yo Gabba Gabba, like way more than my son does. We had ice cream cones, silly cake, water balloons and a homemade Brobee Pinata. I made it out of a paper bag because I was too lazy to handle the paper mache business. It worked great. (okay, it did involve a bit of stabbing) The cake was inspired by these pictures and there are great (and free) Yo Gabba Gabba printables here if you're interested.
