Bitty Baby is an American Girl line of 15" infant baby dolls for children ages 3 and up. Bitty Baby's arms, legs, and head are made from vinyl. A precursor to the line called Our New Baby was first released in 1990, which consisted of Caucasian (with blond hair), African-American, and Asian-American variants. The dolls were marketed as a way to get children to adjust to having a young baby in the house. The dolls were gender neutral, unlike the later Bitty Baby; it was expected that the doll could be a younger boy or girl. .
