Doll with birth certificate

When I was little both my sister and I got this doll and I can't remember what it was called. I remember that every doll was different. They had unique hair, clothes, features, and names. It was packaged it a way that hid the clothing and it had this, like, disolvable hair cover, so you couldn't see whether it was a boy or a girl until you "adopted it". It came with a birth certificate that had the same disolvable cover on it, so you couldn't read it and you had to hold it under water until the cover melted off and then it would tell you what the baby's name was and what gender it was and then you did the same thing to the hair to see what color hair it had. I don't know what made me think of it, but when I did I started trying to figure out what kind of doll it was and it's driving me crazy now! Does anyone have any idea what I'm talking about?
