It's my first time building a house and furnishing and all that, so I had some questions.

I noticed you can place beds in the 2nd floor of the main hall as well as the bedroom wing. My question is, how should I go about doing it? Should I put the children's room in the second floor? The master bedroom in the bedroom wing? Where do the Housecarl and Steward sleep? Will that affect my decision? Is it just preference?

I need some advice/tips here. Not really sure what to do.

Also, is the cellar the only place you can make a Child's Practice Dummy? And while I'm speaking about the cellar...I've bought every single wall sconce, but one of them (in the north room by where the display case would be) is not appearing. I've reloaded multiple times and it never appeared so I gave up. Any ideas?
