okay, i'm realizing i probably shouldn't have posted in this forum. maybe it would have been better to post in my tribe. the thing is that unless you live or have lived somewhere where 110-115 degrees is the norm during the summer, i think it's impossible to provide advice on this. i used to live in chicago, and when i lived there, i would probably would have provided the same (very good) advice that you all are giving me.
i'm not trying to be argumentative. i would like to keep him rearfacing, but I haven't seen any solutions that will REALLY solve the heat issue (beyond what we already do, which is turn the car on ahead of time to let it cool, crank the air way up, give him a cold drink, and the windows are already tinted, which helps block some sun...we've tried the sunshades before and they didn't make a difference in terms of temperature. we also have a garage and try to do covered parking at work, so that the car is not sitting in direct sunlight before we get in). The only way we're remotely okay during the summer here is if there is an air vent blowing directly on us, but there is not one to blow on DS when he's rearfacing. So any other feedback is much appreciated. Honestly not trying to be a pain- I never would have thought this would be such an issue before living here and having a child, but it really is a serious concern...it's not like he gets just a *little* warm in the car. We really feel it is very unsafe. So maybe I should have framed my question as "I'd like to keep him rearfacing but am at a loss as to how to do that and keep him cool enough with 115 degree temps outside. Does anyone with experience in this type of climate have any suggestions?"
