Babe: Three years and ten months
Babeling: Eight months

Guest: Well, I’d better go or I’ll miss my train.
Babymother: Nice to see you, etc.
Babe (to guest): Is there something you want to say?
Guest: ?
Babe: ‘Thank you for having me.’
Guest: Er, yes, thank you for having me.
Babe: Have a nice day.

Babe (during some roleplay or other with babyfather): My mother has died.
Babyfather: Oh dear. Sorry to hear that.
Babe: It’s okay. Her hair is a different colour now.

Does that qualify as her first joke?
