We no longer have an immobile baby. He is on the move. All the time. He is still not crawling regularly (he did it for a second over Thanksgiving break), but his army crawl is fast and efficient. I should be a size 2 from chasing him all over the place, but since I had chips and guacamole tonight for dinner, I don't think that is going to happen.
Tonight, he also took advantage of poor innocent Diddy and used him as leverage to pull himself up into a standing position. I am nervous. And exhausted. Time for more baby proofing.
