i don't know if many kids do this, but anna is definitely going to crawl before she can sit up. every last bit of mental and physical effort is going into this goal, to the point that she is practically doing it in her sleep.
oh, and i highly recommend going through old archives (in my case of personal journals, etc) and tossing nearly everything. i saved accounts of special times in my life -- travel and so on -- as well as my class notes; and was ruthless with the rest. none of it was terribly interesting, and most of it was really depressing. to get rid of reams of paper that i have been carting around for years felt GREAT. it is an extremely effective exercise.
