They’re sitting at the kitchen table, eating berry yoghurt with teaspoons. Mabel has asked me for two baby sisters for her birthday.

‘I’ll name them Elsa and Ana’, she tells me.

‘I want to have a baby when I grow up’ remarks her brother.

‘You can’t lay a baby!’ she tells him with authority. ‘You don’t have a fanny to lay it with!’

‘Okay then’; he pauses for thought. ‘You can have a baby when you grow up and give it to me!’.

‘Like Rumpelstiltskin!’ she roars.

They think they’re very funny.
