We were talking about Santa. Emma decided he would like chocolate and milk for a treat at our house. Then a bit later Emma said she was worried he will get stuck in chimney (due to a song we’ve been singing).
I said “He’s magic and he’ll be fine as long as he doesn’t eat too many chocolate treats on the way”. Then I said “If he does eat too much chocolate then he might get fatter and fatter”. At which point Emma said “And then he’ll have a baby”.
So apparently fat people have babies.
