I have no such qualms. So far, I have been calling my son:
Benji, the Benj, Benjification
Umvi, the Um
Noomi, Noomella, Noomer
Schmooney, Schmoonella, Schmoonmeister
Basically, everything except the name I so carefully picked out for him.
My mother has been calling him Chottu. She has been calling my sister’s new baby Putchki.
