Change Same Value using Parent and Child Animator

I want to change the scale of button using the window animator and then change the scale of the button using the button itself by using it's own animator, but i have tried it and the parent animator (the window) overrides the button animation.

How can i achieve this?

For example my window has Open bool parameter, when the Open is true the window will scale up all buttons to 1 and then when user clicks the button, i want the button increase it's own scale by 0.5 value and scale back to 1, but the window animator overrides the button scale value and don't let me to do animations on buttons.
