I got really spoiled with Lynnie and her naps as a baby. She could fall asleep anywhere, any time. If she fell asleep at home, I could buckle in her car seat, drive to the store, transfer her to the cart, shop, put her back in the car, drive home, and put her back in her crib.
Cece is much more of a "normal" baby. She likes it to be quiet when she naps. She prefers her crib. She likes two specific blankets to be with her when she sleeps. If she falls asleep in the car, she wakes up the second the car is turned off.
In fact, one of the key indicators to me of when Cece started hearing us was when she started getting woken up from her naps by the rest of us talking or the girls playing.
All of this background just goes in to this picture: Cece fell asleep in the van and she really needed a nap. I tried to carefully put her in a bed in the shopping cart, and she was having none of it.
