After the Pejite had kidnapped and tortured a baby Ohm to lure its enraged family to the Valley, Nausicaa managed to convince the baby Ohm that she means no harm to it, placing herself in danger to stop it from the acid lake.
And when Nausicaa herself was burned by the acid in the lake, it is suggested that the baby Ohm sensed what she had done to save it and took away her pain.
And when after Nausicaa had died, sacrificing herself so that the rampaging Ohms wouldn't destroy the Valley, the Ohms used their powers to revive her. When she wakes up, she spots the baby Ohm on the head of another Ohm, waving towards her.
