Our daughter gets sick roughly every time we drive to my parents' house. We already time it for her nap, but it's over two hours, so she winds up awake for the last 30 minutes to an hour or so.
And the worst part is that she almost makes it (so anything that delays onset might actually work). It's brutal getting through two hours without incident, only to wind up with a car full of puke (and a sad, sad little girl) in the last 15 minutes.
I know that what you can see can sometimes help, but she's under two, so I want her in a rear facing car seat, which means there's no way to let her see out the front window.
Has anyone found a way to manage this in a kid under two? I can't easily stop taking them to their grandparents place, but you wouldn't believe how many places puke can get in a car seat.
