Hmmm... I would say that it's a bit young, but if she'll take care of it, I don't see an issue.
The dolls themselves are anatomically correct (but not all of them!) and there's a huge variety. Depending on what she wants or is looking at, there are some good companies for dolls that are on the low end of prices, like under $200. I mean, they're not like Barbies, they have wigs and eyes and elastic and what not...
Also, there is a doll group in tulsa that meets once a month. Here's a link to the facebook
with the info if you'd like to bring her by and look or just hit us up at TNT, we have a whole track of BJD programing and fun and there will be a HUGE variety of dolls. The BJD programing this year will be a joint effort between Tulsa and the Oklahoma City groups and we'll have more info soon.
Hope that helps a little.
