After picking our son Jacob, 3, up from pre-school, while he was having his lunch he said..
'Mummy, I need a new bum'
So I said 'Why do you need a new bum Jacob?'
He said 'Because I fell on it at school and it hurts'
He then said 'I need a bigger bum so when I fall it won't hurt as much!'
He has just started wearing pants so his bum won't be protected from a squidgy nappy!
