Belle use to get sick when she was just a few months old. My husband always teased me as the first two times she got sick was as we pulled into the parking lot at Petco. I would take her on short rides, then increasing the length up to half an hour. I also bought a booster seat for her so she could see out the windows. That seemed to help even more as she could see where she was going. Just be sure and carry a roll of paper towels with you.
