Animating an Object after picking it up

Hi there,

I am working in a 2D project with a player object which is supposed to simply pick up an item to hold it.
I made it so far that you can pick it up by touching the object with 2DCollider and hold it using "SetParent".
After picking up, the object is a child object of my player object.
How do I deal with animations using both objects?
I created an animation with the player object as parent. When i then try to play the animation, the pickable child object just won't move and in the animation it says "missing" on the child object's properties. The animations are in a animator from the player object. In the animation tab it works fine.

What is the proper way to deal with those?

Before "SetParent" in script:


After "SetParent" in script:


It still won't apply the rotation properties on the top Body properties. The bones work fine.
