Thanks. The big one looks good. The seedling is doing the same thing mine were doing a few months ago. All of mine fell over and died for no apparent reason. Everyone told me I was over watering them. The roots were drowning. Get a small spray bottle from the dollar store and barely spray it enough to get the top wet once every 3-4 days. I don't have that problem anymore. My mom has one of those x-mas cactus. I gave it some recharge one day and the next week my mom told me that it made it's first flower in over ten years since she first got it. I told her I helped. Yours could also have too much water. Wait until the dirt is totally dry before watering. See if that helps.
