Dd is 3yr8m RF in a Radian XTSL. We are going to be traveling in the mountains. The last time we made this trip, she got carsick. Any tips to help? Would FF be better? She is behind the drivers seat in a captain chair in our minivan. Would having her in the back seat help so she can see out of the window? Sitting upright with an Angle Adjuster? I'm up for anything to keep her RFing longer. DH is the driver and wants to put her FFing bc the crying taxes on his nerves. (Honestly, everyone gets stressed out!) Thank you!
