We had our hospital tour last night, and during the tour, they recommended going to https://www.seatcheck.org/ to find a location close to you that will do the carseat checks. It's easy to use, you just enter your zipcode and it comes back with a list of places in your area that do the checks. At least for me, it was my local police department.
I thought I would pass along the website, in case any of you were interested.
