Hi, I was just listening to the Almost Up to Possible episode & I don't know if it will be helpful but I called my mom by her childhood nickname until I was about 10. I guess it's because that's what everyone called her! I don't know how I learned that Dad was "Dad" but she was Dolly until my brother was born. I thought it would be rude for a boy to call her Dolly & started calling her Mom. I always thought Mutti was a cool alternative for Mom though I don't remember where I first encountered it.
Good Luck!

I didn't graduate to Dolly until I was older & lazy My earliest memories are of Dolores or screaming "My Dolores" when she left. I'm not painting the best picture – I've stopped screaming when she leaves. But that seems like an awful lot of syllables now. Martha, I don't remember what she called herself & now I feel awful. I'll send this to her to see if she remembers. As for the sibling rivalry – rearing it's ugly head before he was even born! Fortunately, we get along now.
