I was warm up/cool up the car before he comes in it with me. We never get in it unless it's nice and cold or nice and warm!
This didn't start with anything unpleasant either..actually the first time he did it we were going to my aunt's house (he LOVES my aunt) and she lives 7 miles from me and I've been taking him there on a daily basis since he was 2 months. I have no clue what's going on. I wish he could talk to me and just tell me what's wrong. I don't know what else to do.
