So sorry, Nikki! My kiddos both hated traveling with a passion, and when Jack was 3months-12 months, we drove to a village 2 1/2 hours away EVERY WEEK. I wanted to die it was so terrible. We discovered with both of our kids that LOUD music made them stop crying.
With Jack, the first time I came home from the village by myself, I got lost and it took me SEVEN hours instead of 2 1/2, and he screamed the last 3 hours of the trip.
So I blared Def Leppard until I couldn't hear him, and he went to sleep in like five minutes, lol. After that, we found that Simon & Garfunkle did the trick. NO IDEA why, but it didn't even have to be loud. Max likes ringtones.
Maybe next time you have to do that awful trip again, you could have your ipod handy and see what makes her happy.
