Homework and Toddler Beds

Maybe it was happening before, but I think it's a side effect of University because since then, sims simply do not want to be alone while doing things like reading and homework, despite those being things that (imo) should be done alone. (I put that empty desk and reading chair in your room for a reason, young sim, so use it!)

I always redirect to a desk or other seating and usually they'll move and continue their reading/homework there. Not always, but more often than not.
