Poor baby, poor you!! A car sick baby is no fun, 2 legged OR four, I did for Sprocket just like it did for my kids when they were small and had no problems, made sure he could see out the window (car seat/booster seat), and cool air in the face. Now cool air is some times a little harder to do esp in the summer but aside from a little doggie panting or complaining, no problems. It might also just be getting a little older and used to being in the car. Sprocket loves to go ANYWHERE, even the vet, in the car
. Good luck.
