Help! I'm standing and I can't get down!

Mommy has subscribed to 'BabyCenter' since she was pregnant with me and each week she gets an update on what we should be doing developmentally. I always took my time getting to these 'developmental stages' when I was my baby's age but my baby is always ahead of schedule.

This is the email mommy going last night:
"One day you'll walk into your baby's room and find that little person standing up, grinning at you. Many 8-month-olds are strong enough to pull themselves onto their feet and stay there by holding on to you or a piece of furniture. A somewhat comical aspect of this wonderful development is that some babies know how to get up -- but not back down again. They will stand and stand as long as they can hold on, and finally either tumble down or cry to be "rescued.""

....and today, this is what she found:


It doesn't look like she's smiling to me but this has now been the new game the past few days. My baby stands up and cries until mommy comes and 'saves' her.
