I have 18 GC and 5 and 6 GGC are due this next year. Some are step GC and some are bio GC. Most of the GC call me Granny Dee. But, the one who lived with us for 11 years chose to call me Nanny. New Step GC chose to call me Nanny Donna. As I was the Newbie, it was their choice. They had a Nanny and wanted to call me Nanny Donna. They all know what to call me when it comes to time for their Birthday/ LOL
