Colic?

Friday evening might have been our first experience with colic. Isabella's behavior fit the description perfectly. Apparently one of the theories is that at about this age the blocker that prohibits her being overwhelmed by the outside world goes away. So by the evening, the theory goes, she's on sensory overload and can't handle it.
So we lock her in a dark room (I might be in there too).We've experienced the same thing every evening since then, although not quite as bad (perhaps because we know how to handle it now). Brian and Erin said they experienced the same thing with Chloe and it lasted for 3 months. Oooh, the joys of parenthood. Is that why babies are so cute? To prevent their parents from giving up? Because every time I see her I seem to forget that her method of crying has progressed from cute wimpering to oh-I'm-being-tortured screaming. Here are some photos from this last week - including a couple of Dick and Nancy from Mother's Day and some from where we live now.
