Hack, I agree with you that it's not always appropriate. I'm just saying that is isn't always inappropriate either. It's one of those things that depends on the people involved. I have no idea what prompted my SD to begin calling her mom's boyfriend daddy. I don't know whether she was coached or did it on her own. What I do know is that I was introduced to my SD by my first name, and that is what she called me until one day, she called me mama. At 4 years old, she explained to my husband and me how lucky she was because she had 2 mommies, one "real" one and one with her daddy. And that when her other mom got married, she'd have 2 daddies. FOUR parents to love her! She was so excited!
Sometimes I think she had it all figured out before we did. But again, these things don't work for everyone. But for my SD, this is how she likes it, all parents have discussed it, and realize it's not such a bad thing. Our kid is very family oriented, and her titles for her stepdad and me just make her feel better. And isn't that what its all about? Her feelings? It's not hurtful or mean and no one feels rejected just because SD has 2 mommies and 2 daddies. That doesn't mean she loves her real parents any less.
