23 years ago I was thinking all the same things - I was only 35 when he was born and thought I was much to young to be called Grandma - I sat at the hospital while my DIL was in labor and thought of all the names I could be called, but when I first laid eyes on him I would not have cared if he would want to call me Mudpie I would answer and be happy. I now have 15 grandchildren and 4 great grandchildren - they call me what they want - the older ones call me Grandma and the rest call me Ninnie'
