The time change is just a little rough to accommodate sometimes. Nina had fallen asleep in the car for only about 5 min. at what used to be her nap time (now, obvioulsy it's an hour prior according to the clock), and she was barely able to be awakened. I might have let her sleep if she already had eaten lunch, but since I had to wake her up and feed her, she wasn't in a pleasant mood when I woke her.
