Every time I go to my local Sainsbury's, i very rarely find a free Parent & Child space, or any space that is not at the very far end of the car park. I've noticed this more recently as I'm heavily pregnant and have a 2 year old so would love a P&C space. There are only 12 parent & child bays, but there are 18 disabled spaces, the vast majority of them are always free. Given the ratio of parents with young children to blue badge holders in a supermarket at any one time, would it not be more sensible to have, say 12 disabled and 18 P&C bays, or even half & half? I've noticed this in places like IKEA and other big supermarkets too (but haven't actually counted the bays!)
