Princess Daddy

Lyra: I want to wear this nightie, it's my favourite.

Mummy: why's it your favourite Lyra?

Lyra: because it's got Daddy and Lyra and Mummy on it.

Mummy: are you sure it's not Lyra, Mummy and Ellie?

Lyra: No! That one's Daddy (points to blue Princess)

Mummy: How can you tell it's Daddy?

Lyra: (practically rolling her eyes making it clear the answer is very obvious) because it's got a big blue dress...
