Pulling up, crawling, sitting up!

With in the last week Noah has made some huge developmental changes. He starting pulling himself up to standing when he is in his crib. This forced us to have to lower the crib mattress. He also began crawling, and do I ever mean crawling...He is into everything now: the Christmas tree, the dog's crate, electrical cords (those are his favorite!), books, and shoes (another favorite, but more easily moved out of reach!). Noah has also come to love his baby Beethoven by baby Einstein. I can now tell you what is on the screen when certain parts of Beethoven's 1,2,4, and various incidental pieces are on the screen...This means that I am either watching Noah watch this too much, or I am having Noah watch it too much...I haven't figured out which is true yet, but I know this is a way to occupy him for at least 20 mins. I put him in the jumperoo and he is contained and content. I said I wanted him to be crawling by Christmas and they always say be careful of what you ask for...I guess I should heed this advice more often. The final step was getting himself from the crawling position to sitting...He has been working on this for awhile and finally got it last night. He now very patiently walks his hand back until he can muscle the sitting position.
