When I was pregnant with my son it became very very uncomfortable towards the end. I had to do a lot of things on my own since DH was roking round the clock and my family lived not so close by.. and I didn't have any friends to help either. Going to the store and praying I could snatch the expecting or new mothers spot each time was so annoying, especially when I see a woman who is not more than 4 or so months along getting out of her car, or men.. or whoever else decides to take away the spot from me or other ladies who are having such a hard time of it.
I look at them as handicapped spots really. You should only use them if you have to. I know you are an expectant mother, sure, but physically you are fine to walk those extra steps. And yea, it was 9 in the morning, but I went a lot of places at 9 in the morning.
Not trying to flame you but thats just my opinion. Congratulations on the baby
