What are your parents going to be referred to by your LO? For us: MIL: Gran FIL: Grandpa Dad: Pappy Mum: ??? No idea what name my Mum should use, and either does she. 'Nana' is my gran, and my Nana and Mum are both very young (Mum is in her 40s) so Nana will be around for a lot of LOs life, so she'd like to stay Nana. Any ideas for what name we could use? Maybe some sort of derivation of her first name?
