We are one day in to a long road trip (a rt total of about 2000 miles in 10 days to see family) and our son is already not loving it. He runs super hot usually anyway and by the end of today's leg (300 miles?) he had a heat rash and was wailing.
Our ac kind of sucks, we have a black car and his seat (graco snug ride 32) is so padded. Any suggestions to keep him cool?
