My boyfriends son is 1, going to be 2 in September. For a while he called EVERYTHING and anyone "mommy". Now he's pretty much grown out of that, and he has started to address me as Mom. I've got a 5 year old girl, and she doesn't call his dad Daddy, she uses his name. And she calls her own father's gf by her name as well. She knows who is who because she is older. So what do you do with a baby that doesn't understand? And to complicate it, my name and his mothers name are the same. I don't want him to be calling me by my name and then go home to mom and her think we are teaching him to call her by her name and not mommy. I'm trying to be as respectful as I possibly can towards her, despite her being ugly to me and to my daughter. Any advice or suggestions would be helpful!!!! Thanks!
