My girls amaze me with how much they understand. Often, when I talk to them, they will cock their head slightly to the side in a quizzical expression, as if to say, "I'm really trying to understand but you're using words I don't know." They understand phrases like "go potty", "go for a walk", "go to the park", of course, but there are many other expressions they understand as well. One of them is, "it's time to get up". Over the years they have both slept with me at different times, but I got to the point where it had to be one or the other, but not both. They would wedge me in from opposite sides, and I couldn't roll over or move much at all. And I need at least a little space when I sleep!
Last summer, Princess took a liking to the basement where it's cooler, and she is still sleeping down there most nights. Dee Dee sleeps with me, and we enjoy a little snuggle time in the morning, until I realize I've hit 'snooze' one time too many, and say, "It's time to get up!" Dee Dee springs to life and jumps off the bed. Then I say, "Go tell Princess it's time to get up" and she bolts down the stairs, pokes Princess with her nose and runs back up with Princess close behind. If Princess doesn't follow her, she runs back down, pokes her again and barks. It always makes me laugh!
