Fine drivers who park in parent & toddler spaces, but don't have a child present

We fine drivers who park in a disabled parking space, so more should be done to fine people who use parent and toddler spaces when they don't have children present. Most parking spaces aren't big enough to get big car seats out. Should Women really have to walk a mile to get to the shops after giving birth? I suggest we give parents permits and enforce fines to drivers who take advantage of these big spaces. Like we do with those who park in designated disabled spaces.
