@pulickalbrothers We found our son’s motion sickness improved markedly when we got dark blinds for the back side windows so he could only look out of the back. My husband, who also gets it (all his faulty genes you see, they call me ol’ Iron Guts!
) said that it is always worse for him to look sideways instead of straight back or straight forward. My son is the same, it seems.
Not sure if that’s universal or just our family, but it’s worth a go, because the window blinds aren’t expensive.
Fwiw, we didn’t consider going forward facing for it; he wasn’t even 18 months when the problem first reared its head, so until we hit on the blinds thing, one of us would sit in the back with, I kid you not, a lidded soup container (
