In a few weeks, Riley is going to my cottage in Michigan. Its going to take around 3 hours to get there. I took Riley on an hour and a half car ride when he was 6 months old and he got a little sick. Now hes a year old, so hopefully that will help his car sickness. Anyway, how can I make Riley's trip as easy as possible?? Is there any medicine that will help his car sickness?? TIA!
