What to do with old sippy cups?
I'm on quite a few "online yard sale" type groups on Facebook. People list what they're selling or giving away, or what they're in search of. I've found so much for Charlie on these sites either for free or very little. You can always gather yours up and sell them there, or if you'd like to be creative, you can let your kids use them outside to collect sand, dirt, neat rocks or other treasures. You can start a tiny windowsill garden and use sippy cups for little watering cans, ask your child what they think, too! This could be a great fun project for them :)
