I didn't know this small idea yesterday would bring hours of fun. It all started with a Gatorade bottle that I let Daniel put beads in since he was complaining he was bored. That was fun for a good 30 minutes. Then Travis had the idea of filling the bottle with water. Serious hours of fun shaking a cheap old bottle filled with beads. Even Zachary loved it! Daniel kept the bottle by his bed last night and played with it all morning today. I love it for Zachary because it's somewhat heavy with the water in it, so he's working those tiny muscles a bit too!
