Most birds will want to climb to the highest point on your body. Don't be afraid when she climbs up your arm, and onto your shoulder or head. Speak soothingly to her as she climbs and inspects you. Relax and enjoy her curiosity in you. Do not feed her anywhere except in her cage.
Some birds require free time outside of the cage.
If so, make sure you cover windows, mirrors and large glass panels to prevent her from crashing into them. She does not know there is a barrier there to hurt her, she thinks it is all open spaces. She has to be supervised during the exercise flying time. She will peck and chew on almost any surface. If you have toxic plants, either take them to a room where she won't be, or give the plants away.
