Was it "Little Mommy" you're thinking of? The book is all about how the little girl spends her day pretending to be a mommy. She has three children Annabelle, Betsy and Bonny (her dolls). Billy is the daddy - he has a little blue car. And she does have tea with a friend and her dollies. And there's a picture of a tea party with her, Billy and the dolls, but they're pretending to have dinner.
i'm looking for a book i had as a child about a little boy and girl who play mommy and daddy. all i can remember is that the "daddy" went to work and the "mommy" stayed home, but i can't remember what either of them did. i want to say the daddy was a doctor, but it's not Doctor Dan the Bandage Man. could be a different Dr Dan book, but not that one. this one was about the children who were playing make believe and i want to say they had "tea" at some point. maybe a doll got sick, but i'm not sure. please help me - email me if you can -- bcain@nando.com thanks!!
