Maybe I'm splitting hairs here but is 'Ninni' really pronounced the same as 'Ninny'? To me 'Ninni' would be pronounced more like 'Nee-Nee' if that makes sense lol, where as ninny would be pronounced more like 'ni-nee'. Definitely a difference there in my opinion.

I don't know...I'm from the south so maybe in New York/New Jersey it sounds the same.
