As someone who has a disabled sibling who has genuine need for a blue badge, and all the extra space a disable bay allows, and also as a Mum of one nine month old, personally, I have no issue with this at all. People have babies by choice, and if getting in and out of a car in an ordinary space in a supermarket car park is of such an inconvenience to people with children, I think they need to reevaluate their priorities! Having a child is a choice and people should be able to deal with the consequences. Having a disability is NOT a choice. I would gladly get rid of all parent and child spaces if more disabled bays were needed. Parent and child spaces are a luxury, NOT a necessity and I have to say, I'm a bit flabbergasted anyone would have a problem with this..... Comparing a disabled bay with a parent and child space is actually pretty appalling, not mention insulting, too. Having a child is NOT a disability, and to even compare the needs of these two different groups is pretty shocking. I cannot fathom how anyone can genuinely feel they have a 'need' to park in parent and child space as much as a disabled person 'needs' to park in a disabled bay.
Just because I chose to have a baby, doesn't mean I should just accept inconvenience as par for the course. It's sounds like I deserve punishment because I chose to have a baby! We should be a caring society, which cares and helps people who need it for example by providing disabled AND parent and baby parking spaces, to give up a seat on public transport for disabled AND pregnant ladies, to provide spacious toilets for disabled AND those with prams. I don't think it's fair to infer that those with children deserve to struggle because they chose to have a baby! Procreation is a part of life and society should be caring!
And just to answer the original question, I wouldn't have an issue with a disabled person parking in a parent and baby space but I do have issues with those parkng in the spaces when they have no need! When no parent and baby spaces are available, I try to find a space on the end with space to one side or failing that, I will drive to a different car park to see if a space is available there. I don't want to be in a position where I have no alternative but to leave my baby's pram on the road so I can reverse out a bit in order to be able to open the door wide enough to get him back in. That's just downright dangerous!! i don't think parent and baby spaces are a luxury at all, I think they should always be provided, not necessarily at the front of the car park, put them at the back if you want, but I agree with others that have said that they could not open the doors wide enough to get their baby back in if they hadn't been in a parent/baby space.
