Leia is now standing without holding on to anything.
Its been less than a week that she could pull herself up to standing unassisted. Now she'll climb up on something and chatter until she has our attention. Then she'll slowly, deliberately, one hand at a time, let go of whatever she's using to balance herself. After five to ten seconds she starts to topple over and so either falls or grabs on to something. For those few seconds she has the biggest, most proud smile of anyone on the face of this planet.
We haven't been able to take a snapshot of it yet. Still trying.
