This is probably TL;DR and can be summed up in the first sentence.
Am I being a big baby, or is it reasonable for me to ask for parking accommodations at 24 weeks? I park about 500m (1/3 mile) away which isn't too far on it's own, but I have to cross a pedestrian overpass (over traffic) with a steep ramp on either end, and it's been 30+ degrees (86+ in f) with high humidity here for weeks, and will be for the foreseeable future. In the mornings I get light-headed walking over the overpass and my legs feel like lead (plus the general slowness and shortness of breath). Too much physical exertion has been causing worse BHs. At the end of the work day it is worse (especially since it's way hotter). I can take a detour and add 100m or so on to the walk, to avoid the overpass, but then I have to stand at a busy intersection for several minutes in the sweltering heat (hey, I'm from Canada, not FL - this is sweltering for us) waiting for a walk light. If I try to rush I get pulling pains in my lower abdomen and shooting pains in my vag. If my feet are swollen that day, my skin actually hurts. Now, none of this is high BP or edema or an actual medical condition, other than the "condition" of multiples itself. Am I being a baby if I ask for a note from my doctor? With a note I can get a pass to park at a meter nearer my building. I phoned the office this morning to ask how to go about getting a form signed and the receptionist seemed like she was almost laughing at me, saying I could try but she didn't know if my doc would sign such a note. I tried faxing the form to my doctor's office 4 times today but it never went through and now I'm wondering if I should bother. Today, I am in a pay lot, even though I pay monthly fees at another lot, in order to be closer to work. It will cost me about 1/4 of what it costs me a month to park in my regular lot to park here today. That's how much I hate walking.
ETA: It's not like I never walk, either, which has me second guessing my actual "need". I walked about 1.5-2km with DD to and from the park this weekend, but it was at our own leisurely pace, with lots of breaks, and the whether was very cool.

Re: Parking accomodation
All the doctor can do is tell you no.
I used my dad's handicapped at all my last appointments for the triplets instead of walking the 1/2 mile. In the end, they told me I should have asked for accommodations. . And this is in downtown Chicago!

FYI using a handicap placard with out the person with you is illegal.
I'm guess if you are at work, you'd also be carrying a lunch and pocketbook too? I would definitely ask for a parking permit closer. It's not worth it to put that strain on you or the babies. Don't let people think you are being a baby.
Good luck!

Sorry no just saying that in general. Too many people take advantage of the handicap spots and it sucks. I did not get one till my daughter was over 2 and still not walking with out assistance. We don't use the placard much now. Just kind of a sore spot for me.
I think you should def ask. At my work, you just needed a doctor’s note and you could park in the handicapped parking.
My walk was a lot shorter than yours. Your goal is healthy full term babies, so I hope they accommodate you!

It's not like she is taking something from a disabled person (and I say this as someone whose husband has a placard).
