Sitting up on my own

Every day I am getting bigger.  Every day I am getting stronger.  Every day I learn to do something new.  I have been on the verge of crawling for a few days now.  I get up on my hands and knees (sometimes hands and feet) and rock back and forth.  I can move slightly forward by hopping like a frog, but when I try to pick my hands up I tumble face forward to the floor.  My hands don't seem to want to move.  Since I can't move at crawling-speed yet, yesterday I decided to try something new and found that I don't have to stay horizontal all the time.  I learned that I can push myself up to sitting all on my own.  Unfortunately this means that mommy and daddy aren't as quick to come help me sit up now so I get quite frustrated.  But, I have a weapon...  I have found my whiney voice and this seems to get their attention pretty well.  Be sure to take the new poll and vote whether you think I will be crawling before the new year or not.
