I used to be the car sick queen. I used to throw up every time we were in the car for an hour or more. I vomited almost every time we drove to my grandparents. I was getting really good at vomiting in a plastic bag. I hated it. I guess it started when I was two. We went to Santa Claus Land and I got so car sick that my mom had to throw away my car seat at a rest stop in the trash can. My mom said it smelled too bad to keep it.
Noah is unfortunately following in my footsteps. It's become a running tally about how many states Noah has thrown up in. My mom used to give me car sickness medicine hidden inside a spoon of peanut butter. I used to not be able to swallow pills so this was her "remedy" for this. I still can't eat a spoon of plain peanut butter without gagging. I really think that car sickness is something you grow out of as you grow up. Hopefully Noah will get over his bouts of car sickness soon.
