We drove from the East coast to Colorado with Morrissey 4 years ago, he did really well, we stopped every couple of hours for a break, also he had his blanket and some of his toys.
Hopefully your baby will look out the window and enjoy the view as you are driving, ( and sleep!) good luck! Morrissey's mommy.
