We are off on holiday in 2 weeks and this involves driving for at least 6 hours to get the the caravan site. My DD who is 13 months just hates being in the car. 30 minutes is kind of her limit. She is usually a good sleeper but in the car no more than 45. Anyone have good tips on how to entertain her. I can't really sit in the back for too long as there is not much room (5 year DS is also in the back) and I get travel sick in the back. Could DD have travel sickness. She has never been sick so is just wondering?
