The only ones I regret are that she also has the Bitty Baby and the Bitty Twins. Those were pretty much a waste of money in our household. DH's parents bought her Bitty Baby when she was 2. She has never shown much interest in it at all. She may have played with it a few times over the last almost 4 years. They bought her the Bitty Twins for her 3rd birthday. The twins have received a llittle bit of playtime, but not a whole lot. Really from the time she was 2 (got an 18 inch non AG from Santa that year), her interest has been pretty much solely with the 18 inch "older" dolls.
Interesting - We got a Bitty Baby at a yard sale, and my DD (who was 3 in October) loves the doll but she has also lately taken to writing on things, and unfortunately she wrote on the BB's face. She noticed the AG catalogue and has been asking for Bitty Twins, which we were thinking of getting her for her 4th birthday (assuming she is past her scribbling stage, which she should be!) Now I'm wondering if that's a good course of action...she does go through stages of carrying "my baby" everywhere and changing its outfits but not to that extent. Hmmm...
