Bit of an obscure want but hopefully someone can help! The build a bear shops used to sell toy wheelchairs to go with the teddies, but have now discontinued them.
If anyone has one for sale, please let me know! Theres something similar on ebay but it looks like the price is going to go a bit too high :(
I've got an idea for my disabled sons birthday pressie, and it involves a singing teddy, and hopefully a mock up of his school uniform :)
