When the first one came, I was Nana. Then came the second and he already had a Nana (her other grandkids call her that) and I didn't want him to think anything that I did came from his other "Nana" so to him I am Grammy...lol I get a little confused sometimes on who I am. I just hope they don't have issues...she's my Nana...no, she's my Grammy! They are only about a year apart.
