Tessa, I don't know how I lost track of your thread, however I have found you and just played catch up. I'm glad your OS had an explanation for your knee cap that seemed to give way, however if you have any other unexplained falls like the last one, I would give his office a call and let him know because he may want to check it again. Who knows, maybe there's and exercise that you can do to strengthen the muscles around your kneecap to stabilize it. Just a thought!
You certainly do have a precious little boy and girl there, sweet!
Also, can you do me a favor? Can your remember that, yes you are young, but you are not invincible! Do take care and go just a little bit slower! We care and we don't want to see you hurting!
Stay well and enjoy that young family of yours, there's a lot of good years ahead of you!
