We went travelling (car) when Ds3 was 8-9 months old. We were doing alot of driving over the 5 weeks. We took new toys like cars and very bright things in the car.

I know driving is different to flying cus at least they are buckled in one spot in a car plus Ds3 wasn't crawling.. Can she look out the window? it might really fascinate her enough for a little while.. Or buy her a toy mobile phone lol.. That used to entertain my kids when nothing else worked lol
