Anyone got any tips? My ds has suffered ever since we took him out of his baby seat and put him in a booster. The only thing that seems to stop it is having him in the front seat, but it's a pain on long journeys, especially at night when he invariably falls asleep and DP and I are left trying to shout a conversation between the drivers seat and the back. Also - not sure if it's legal to have a small child in the front (he's almost 4). I was wondering if any of the anti-travel sickness pills work, and if there are any homeopathic remedies we could try. And whether one of the more deluxe boosters - with the head rest - would be better for him than the version we have.
