My great nan was 90 when she passed when i was PG with DD1 she was in a nursing home and was physically unable but mentally boy oh boy... she could make DP blush with her jokes and didn't mind throwing ina few expletives when needed.
I walked in once and she looked at me and said "you look a bit round, is that natural" because she wanted me to be PG
Silly things like "that man better hurry up & make an honest woman of you before you run away with the milkman" then she would quickly change her mind and say something like "not the milkman, the IT tech... get with the times"
