Just crawl already!

So, I've read several different places that when a baby is fixin' to do something new, the sleep patterns can be disrupted. I'd say, based on experience, that is right. For a few weeks now Isabel has been up on her hands and knees, and a few times has rocked back and forth. It looks like she's is on her way to crawling (although, the anthropologist in me wants her to skip crawling altogether and just walk. Crawling isn't necessary for walking, and many traditional societies skip crawling. But, the mom in me wants her to do everything, so I'll be happy either way). She's been having trouble staying asleep the past few nights, and times her crying to when we are headed to bed (coincidence?). Last night was the same scenario, so we just brought her to bed with us. She stayed there all night, and I'd say the 3 of us did fairly well together. Until 3:30.
Isabel was wide awake & whiny at 3:30 am. This wasn't in between sleep cycles, this was full on awake. She spent about 30-ish minutes up on her hands and knees rocking and whining. When she finally decided she wasn't going anywhere, she started crying. So, Ryan and I started our day at 3:30. Needless to say (than why am I saying it?) we won't be staying up until midnight tonight. She went back down about 5:30 for her first nap, and I have no idea how long that will be for.
She's just been off lately, partly because of the cold and partly (hopefully) because she's getting ready to do something big. I'm hoping for a mobile New Year so we can get back to the greatness of sleeping!
