I came upon these recently, and wanted to share.
Free music! Songs of Love is a foundation that provides personalized songs for kids and teens facing medical or emotional challenges. You fill out an online profile of your child, and about a month or so later a CD arrives in the mail with the finished song. We just got one for Max that's very boppy and all about his love of transportation; we play it in the car and he loves it.
Free professional photos! The Littlest Heroes Project is a group of good-willed photographers who offer free photo sessions to kids with disabilities and serious illnesses. I filled out an online application, got approved and now I just have to choose a local affiliated photographer and pick a date. Hard to resist—professional photos of Max make me giddy.
If you've found any good services for kids with challenges, let the rest of us know!
