What will my grandson call me

Sebastian is my first and only grandchild and he is a whopping 4 1/2 months old.  When he was born I felt I was too young to be a Grandmother, Grandma, or Granny.  With more and more  grandmothers taking on cute names for the kids to call them it seems to be an over abundant amount of GiGi's, and MiMi's, Maw Maw;s, Me-Maw's and so on.  I wanted a fun name, so I said he could call me Honey. Well when he comes to spend the weekends with me Honey doesn't even come close to the honor to be his Grandmother.  I can't even form the words Honey loves you, the only thing that falls out of my mouth is Grandma loves you. The smile that he flashes me when I say that just makes my heart melt.  I may be young cough mid forties, but I believe I will just be Grandma, but whatever he decides to call me I will be there to answer with Love.  He is my heart and I am thankful that I get to be a Grandma
