Last weekend Sofia and I went to Las Vegas with my Mom ( Kathy ) , Coco , Janet , Paul , Matt , Babe , Ryder and August , who was born two weeks after Sofia . I would n't say she loved the long car trip , but she did tolerate it . Mostly she slept in the car seat , then she 'd wake up and complain , and we 'd appease her , then she 'd go back to sleep . Timing the feeding seemed to be key .
