A young girl takes a bath in a room full of men wandering back and forth. No nudity is shown.

No sex. A young boy and a girl swim nude and lie in the sun, no genitals visible. Grown up nude males wash themselves outside in the snow, filmed from quite a distance. Neither of these scenes has any insinuation.

The fighting scenes of the robbers are benign and full with jests at the opponent. No blood, visible or intentional pain, more like wrestling.

A lady gets mad and says a bunch of swearwords in Swedish. English viewers or viewers that don't speak Swedish won't understand these tho

None. (my soundtrack is Swedish and I cannot judge that, but the Dutch subtitles contain no profanity.)

No drugs. No smoking. Mild beer consumption at 'robber parties', without intoxication.

The screaming witchlike birds are kind of scary and will probably upset very young children. They charge at the children screaming with high-pitch voices that they are going to take the children, insinuating eating them. Adventure style, the children hide, and there is no real danger. Still, somewhat scary.
