I ask why 'baby on board' signs seem to wind drivers up so much...
In the back of my scruffy, mum-wagon Vauxhall hangs a sweet caterpillar in rainbow colours, warning other road users that I have a 'Baby On Board'.
It's been there since the day we drove our first baby home from hospital - crawling at about 15 miles an hour and stopping every few minutes to check Harry was still actually breathing.
