It has also allowed me to give W the benefit of the doubt in certain cases recently - I would've chalked up her behavior to being disorganized and flakey previously, but instead I trust that she did things in a good way and everything was fine. And if she forgot because of whatever reason, it's okay because I forget to do $hit too and it's not because she's a bad planner.
I think this is one of the last pieces for me to fall into place. To not judge her on what she is doing as a parent, what she forgets to do and/or what activities she chooses to participate in. Good for you on recognizing and not falling into the trap.
