Friday I have to take our new car in to the dealership to have some accessories added to it. They will have it all day, so they are giving me a loaner car. The kids and I are going to be running around doing errands, etc. while they work on the car. Even if it was otherwise an option, which I have things I need to take care of on Friday, we live too far from the dealership to take the loaner home for the day or to DH to help us with the seat. I already asked about the mileage limits on the loaner.
DD is in a Britax Boulevard, which is NBD for me to install in the loaner and reinstall in our car at the end of the day, but DS is in a Britax Frontier, which I have trouble getting tight enough by myself. Usually, I crawl into the seat, and DH has to pull on the latch strap to get it tightened. I didn't ask for help when we were testing cars, but the sales guy volunteered that dealership employees are specifically NOT allowed to help with carseats at all b/c of liability.
The way I see it, I have three options.
1) I can drive around all day (and then 40min back home until DH can help me again) with DS in a seat that isn't strapped in as tightly as it should be b/c I can't get it tight enough by myself.
2) I can try to put the Frontier in with the seatbelt, but I have never used a seatbelt on any of our seats and have no idea what I'm doing, which should be a very interesting experience b/c I'll also be corralling two kids in the dealership parking lot by myself while figuring it out. (Admittedly, I could practice on our car at least on Thurs night, I suppose.)
3) I have DS' Britax Boulevard, which he just barely, barely (maybe 1/4in) exceeds the height limit on, and he could use that. He's still within the weight limit by a ton.
I feel like #1 is just a bad, bad idea. #2 seems like a good idea until I imagine trying to keep DD (especially) from being run over by cars in the dealership parking lot while fighting the seatbelt. #3 seems like the best of the awful options, but I'm leery of using a seat that he's outgrown too.
