Cochlear has a koloa with a CI, Advanced Bionics has 2 monkeys with implants (male has 1, female has 2), and Med-El has um Buster the Bunny with an implant. You could probably ask about them through the manufacturer's website and get one through them, if you want an "official" one with an implant that's similar to your daughter's.
You would think that they could throw in a doll for the kids for the price you pay for the implants
Hmm I wonder if the "toy processors" would work on the dolls I make. It doesn't give dimentions though. Do you know how big the koala is? I know I could work with the wigs on the dolls to make the processors work, if the design of it was not to large for the size doll. I am not currently selling my dolls, but in the process of deciding if I want to make it a business, but my target market was for sensory processing disorders. I made a few weighted dolls for kids like my daughter. The site is under contruction but I can link it: Home I could do dolls for other needs to on special order, maybe.
