If you marry your boyfriend, then yes, you will be step-grandma to the baby. When my sons were babies, they had 8 living grandparents.... maternal grandma "Mimi"(and her mom, great-grandma known to all as; "Grandma Shaw") & grandpa "Poppa" (so Mimi & Poppa go together) Poppa's mom, great "Grandmother Higgins"(so that's four from my side). Then also on my husband's side; "Na" (my husband's mom) "Grandpa" (my husband's dad) his wife; "Grandma Sue" and Grandpa's mom, "Nana" The only one not by blood, is Grandma Sue, who told us that we could have the kids call her whatever WE wanted them to call her. She suggested "Aunt Sue" if we didn't want Grandma and that was very sweet of her, but we thought "Grandma Sue" suited her well. She has always been a very loving, giving, generous grandparent to my children and still is today. She is just as much a true grandparent to my kids as all the others are. Just be loving and sweet to the baby and you will be "in the loop" for sure. Good luck. D. N. xo
PS... Grandma Sue ALWAYS sends each & every family member on my husband's side, a birthday card & gift, as well always being generous at Christmas. She really stepped up to the plate to be a wonderful grandma but has never interfered or overstepped her bounderies with any of us. We love her as we love all our other grandparents, for her loving ways and general kindness. She has been a "real" grandma to us and happily became a real biological grandma to my husband's brother's (Grandpa & Grandma Sue's son) baby son, 15 months ago! We are so happy for her and my husband and I are the proud God-parents of baby John!!!
