Han uppför sig som ett barn.

[davidculley]

English Translation

He behaves like a child.

Is there a difference between “han beter sig” and “han uppför sig”?

[morbrorper]

I would say they are practically synonymous, with “uppföra sig” having a judgmental component.

One would say “Uppför dig ordentligt!”, not “Bete dig ordentligt!”.
