E.,
I don't know where your are exactly. I would suggest The Women's Shelter in Arlington. My children and I were blessed by the shelter in 2000 and I always think of them when asked about where things like that can be donated. I prefer them becuase they do not resale them but instead have them on hand for children who leave their homes, often time in the middle of the night, with nothing but the clothes on their backs. My duaghter now age 12 still has the rather large dinosaur that another child who was leaving the shelter gave her upon our arrival. Here is a link to their website to find out where to make the donation.

I hope that this is a help.
God Bless
