Five months old yesterday

Can you believe it? Miss M is five months old! Soon enough she'll be asking to borrow the car! We celebrated her five month birthday with a hearty round of congratulations for mastering (well, almost mastering) yet another feat of strength - sitting up by herself. For about the past week she's been pretty solid on the tripod position, but yesterday we were all playing on the bed (drop the baby and she goes bouncy, bouncy, bouncy, yay!) and given the nice, cushy protection of the comforter we thought it would be a great time to practice our tripod skills. I sat her down on the mattress and we were a little surprised to see her sit straight backed, balancing herself, no hands on the matress, for a good 20 seconds. Yes, she still topples over. Yes, I still have to place her in a seated position. And yes, it still only lasts 5 to 20 seconds. But we're making progress! And she's ahead of the game - books say about 6-8 months they usually start this. I love my little wunderkind. I'm sure there's a trade-off coming for all these super-fly fast motor developments -- like she won't be potty trained until she's five or something.
