Put your baby in the boot and back into the road to load them,

so you can stop traffic while you load them and annoy all the people who want to drive out of the car park?
That wasn’t quite thought through was it? And dangerous for the baby. All so selfish people can justify and argue blind that the people that those space were designed for don’t deserve them as much as they do?
Is it BINGO if I say “it’s in the bloody name”? Parent and child, so sorry if you’re learning comprehension is so bad you think it actually says “special spot for you and your precious car and precious self who is too special to use the normal spots like those commoners” 
Obviously nobody disputes disabled people using the spaces if the disabled bays are full. This is about the frustration felt when a perfectly able bodied person uses the space which is specially created for those who need it more. And I get your frustration OP, especially as mums with babies are sleep deprived and full of raw emotion and stress. You don’t need people saying “get the fuck on with it” like they’ve had an empathy bypass in order to justify their selfishness.
Also not to shine my halo too much, I never considered parking in a p&c bay until I had need to... like the majority of people I assumed...
