The baby plants need to be put in pots of their own because they will crowd the mother and take nutrition from her.. The mother plant needs to be repotted because she might be root bound. You take a baby and its root and plant it in the soil. It will look a little sick for awhile and then perk up and grow.

I read somewhere that you should replace a plant's soil at least once a year. I've transferred the plant before, but that was when it was I had first gotten it from my grandmother. Now, it has a bunch of pups popping up all around the pot and I'm not sure how I can replace my aloe's soil without killing a few of the babies...
