Thanks guys
I've tried holding him in the car just to see if he is better but he still gets sick and also in his crate covered. My brother got him a carseat but he does the same thing.
It's easy not to go in the car at all to avoid him getting sick,lol but I'm gonna start slow and work him up to it
There was only one time he didn't get sick, when I was taking him to his play group I kept saying where gonna see your friends, lol
