Well, I always wanted to be called Granny, like on Beverly Hillbillies, but that was the step-grandmothers name on the other side and she already had grandkids, our first. Then I thought I'll go with Mom-mom, that what the babysitting kids always called my mother. No, that's the other grandmother and she already has grandkids too. So my other child say how about Gam-gam or Gammy. That's what we went with. Well, when he started talking he called me dd and it has stuck. I like it and it's very original. Weren't not sure why he says it but that's ok with me. It was very confusing at first when people would say grandma to him and he didn't know who they were referring to. Some people think that is my name and others think I'm the caregiver instead of the grandma. We're not sure how he spells it, he's almost 3, so we are just going with the 2 lower case d's for now. That's why it's my screen name.
