Best baby doll recommendations to prepare toddler for new baby?


Looking for books to read and baby doll suggestions to help prepare my daughter for her new sister. My daughter is 16 months and loves baby dolls, but hers are all simple and I want one a little more advanced to get her for Christmas. Maybe something that cries/coos, has a bottle, and has the options for changing diapers, but doesn't actually wet itself. Her little sister is due in February, they will be about 20 months apart.
