A has started standing (while leaning/supporting herself on something else) a lot more lately. I've noticed that most of the time she is standing with her knees locked. I know that locking your knees is generally not a good think for extended periods of time - should I be worried about it with her for the ~5 minutes she stands at a time?
Re: locking knees while standing
Okay, after a cursory look into this, I found that it is possible to pass out when you're standing for LONG periods of time with locked knees (I won't bore you with the anatomy of why), but it appears that generally only happens when the body is under other forms of stress simultaneously, such as dehydration, being out in hot sun or under hot lights, stressful situations, etc.
No reason to worry about little A!
