Are high-quality/high-cost baby dolls (Corolle, Bitty Baby, etc.) worth it?
We're planning to get DD a new doll for her baby sister's arrival. She'll be ~3.5 yo at the time. She currently has only one "real" doll, which is a Circo 14-inch doll. It's just a basic doll -- cloth body, plastic arms, legs, and head. (http://www.target.com/p/circo-feed-a...ot=medium_1_17) She plays with the doll at least some each day. She's had the doll for a year and it's held up just fine. The plastic head has some weird scuff marks, but they're not terrible and don't bother DD at all. Size seems perfect for her. I'm happy with the doll and she hasn't felt "cheap" even though it was.
In terms of the new doll we're going to get her -- I don't want to just buy a second Circo 14-inch doll, because they all look identical and I don't want to just have 2 of the same doll. Do you think the higher quality, expensive babies like Corolle or Bitty Baby are worth it? What makes them better than the cheap Circo-type doll? If you think they're worth it, are there other brands besides Corolle and Bitty Baby I should look at? If you don't think they're worth it -- any suggestions of other less expensive baby dolls that would fit the bill? I'm basically looking for a doll that DD can "take care of" with me while I'm taking care of her baby sister.
(and as a semi-seperate question -- if you like Corolle, anyone have the Les Classiques vs. the Calin? I know Calin gets a ton of love around here, but I think I prefer the 14-inch size of the Les Classiques baby instead....)
