Well I have been standing up since April 1st. Each day it gets easier and easier. I certainly know how to master things quickly. Some things I have learned so far:
1. After standing up, only reach for the remote with one hand (otherwise kaboom).
2. If I fall make sure I don't hit my head on my toys (see pic).
3. Mommy gets scared if I let go for more than 5 seconds.
4. Laundry baskets tip over unless there is clothes in there.
5. It is harder to stand up with a football in my hand, but I can't cause a fumble.
