Holly was baby, and Rosie was Mummy this afternoon:

Rosie: "Do you want some milk from my boobies, baby?"
Holly: "Yes please!"
Rosie: "Is that good? What does it taste like?"
Holly: "It does taste like watery milk."
Rosie: "No. This boobie makes milk that tastes of... er... apple juice, and this one tastes of orange."
