Just today it dawned on DH and I that our 17 month old DS suffers from travel sickness. We now both feel mighty guilty for being less than sympathetic when he's started to whine after an hour or two in the car. Since we have now had two journeys where he has been violently sick on the way home, I think there is no doubt what the problem is.
So what can we do about it? Can you get those sea sickness bands for toddlers and do they keep them on? I'm guessing there won't be any medication available. He's too young for us to make sure he looks out of the window etc. or to distract for long with songs and games.
