Last year for my son's first birthday we collected items for Give What You Got. They provide birthday care packages for children in KC area foster homes. For some, these are the only presents they'll receive on their special day. And, many of them are forced to move from family to family with only what they can carry, having to leave toys and other things behind each time. To help with this, one of the things you can donate is duffle/travel bags so they don't have to haul precious items in a trash bag and risk it ripping.
Give What You Got collects for ages 1-18, both new and gently used items. It's a great way to clear out some things your kids have outgrown or that your house doesn't need (like photo frames, CDs/DVDs, etc. that older ones could enjoy).
