Cataholic...no worries, it's not nosy. She was unofficially diagnosed with a discoid lateral miniscus in her right knee. It has popped since birth, but until her four month checkup, her doctor was unconcerned. At that appointment, though, he sent us to a specialist to have it looked at. The doctor said that in order to 100% diagnose, she would need to be anesthetized for an MRI. We both agreed that was unnecessary because it doesn't cause her any pain. If it does at any point in the future or affects her developmentally, we will discuss our options (ie surgery). It's basically that the cartilage between her shin and thigh bones is misshapen. Some people never have any problems other than the fact that they have a poppy knee. We are just keeping an eye on it and praying it never needs further investigation.

The "practicing" really isn't anything. I'm doing it simply as a barometer for when I need to lower her crib mattress. At this time, she only hangs on for a couple seconds usually before toppling over. The pictures were taken the first time she held on for long enough for me to get my phone and take a few photos. She was leaning against the side. We were never instructed one way or the other to not help her bear weight on her legs, so I didn't give it much thought. I figure she will do things on her own time, but I don't see anything wrong in giving her a little nudge when she is trying to roll over or pulling her up from a flat position on her back into a sitting position when she has ahold of my hands and engages her abdomen herself. I don't think we overdo it, though.

And I'm not too paranoid about milestones at particular times, because I have heard too many stories like Jonah's, where babies skip crawling or are "late" to roll over or sit up. She will do her thing when she is ready to. Like I said, we help her or give a little tug or a little nudge every now and then. She already sits up unassisted, but not for very long.

anyway, sorry for the long answer hahaha.
