How old? Ages 3-6 really should have Bitty. The older ones can usually handle the regular dolls.
My girls have Bitty, Molly, Samantha and Kit. I personally like the historical dolls better than the ones that look like your child.
Sadly- they're now retiring some of the dolls. Kirsten was retired last year. I think they're going to retire Felicity too. Samantha is being retired at the end of the year. And I have a feeling that Molly's next, she is the last of the original 3 that started the whole thing.
Anyhow, my girls are teenagers now, but they LOVED their dolls growing up. My mil made clothes for them, and I have a container full of clothes. My mom bought them furniture. We have a tea set. We have a cat and a dog, their names escape me right now. And Bitty Bear, I don't know if they even make Bitty Bear anymore.
I was putting things out for a yard sale, and my oldest said "you aren't selling any of our AG stuff are you?" Um NO.
Molly needs to go to the doll hospital. She lost her arm a couple of weeks ago. She's got some pretty loose legs too. But my oldest got her when she was 6, and she'll be 17 in January

I sent off an email to make sure they're still taking care of the "retired" dolls, since we've got Samantha, and they said they'd take them, until further notice. The doll hospital is neat, they come back with a hospital gown, a get-well balloon and a bandaid

IMHO I think they are well worth the price. I never bought another baby doll after we got Molly and Bitty. And my kids could have cared less.
