L.C.
The only thing/places I could think of are the following
Hope Children's home- store is on 275 & Fowler- old Pier 1 outlet. This is a thrift store. So toys are a donation & tax deductible, and yes they do sell them. The Children's home has an open house once a year as well as a monthly news letter. http://www.hopechildrenshome.org/ They are a christian organization who takes in foster kids. they live more in a dorm/ boarding school type setting than a regular foster home. they accept other donations, box tops for education, etc, as well as supplies, cleaning supplies, clothes etc. I have know about them for several years & have been pleased with their work with kids which is why I keep donating items, box tops etc whatever I can. I don't know if they have ways for kids to directly help out. You can contact them & see. The people there are very nice.
You can also try Metropoliton ministeries- also don't know what they have for kids.
