Can I have a baby?

Daughter: 'Can I have a baby in my tummy?'
Me: 'No, you're only a little girl. Little girls can't have babies in their tummies.'
Daughter: 'Oh when I'm bigger can I have a baby in my tummy?'
Me: 'Yes, when you're bigger'
Daughter: 'Maybe when I'm ten I can have a baby in my tummy.'
Me: 'No, when you're an adult you can have a baby. When you've been to university and married someone lovely, you can have a baby in your tummy.'
Daughter: 'I'll be bigger tomorrow. Can I have a baby tomorrow?'
