I did once. I started off with an elderly couple, and they were raising their granddaughter who was only a child. This was before I was using any mods. The little girl was only 2 days away from becoming a teen when both the husband and wife died on the same day. That was the end of the game for me because the game culled her. If I would have it set up in MCCC mod, the child would have been "adopted" by another family in the game. I was fairly new to Sims 4 too, so I was still learning how to avoid stuff without mods.
