Danny, aged six was visiting his mother and his new sister in the maternity hospital and getting very bored. He wandered in to the next ward to talk to an old lady patient.
‘How long have you been here?’ he asked her.
‘Oh, about six weeks,’ she told him.
‘Can I see your baby? ‘Asked the little chap.
‘I’ am afraid I don’t have one’, she said.

‘My your slow,’ said Danny. ‘My mummy’s only been two days and she’s got one already’.
