Where can I find the life-like baby dolls to give to my mom with Alzheimer's?

I read an article posted on your site not too long ago about the benefits for some female Alzheimer's victims have from having a real life-like baby doll. I don't recall the article stating where to purchase these dolls. I would like to buy one for my mommy. I think she is a prime candidate to benefit from having a baby to hold and care for again! Please assist me in finding where I may purchase one as I know one cannot buy them at a local department store since they are specially made. Thank you for your time and help.
