Did I miss something?

Hello everyone, let me introduce myself, I am moron. So as it turns out I had my 9 year old help bleed the brakes when I was finished this job and I totally forgot how much kids like switches. Yes, I have a roll control valve and the switch for it was inviting to those little fingers. It is hooked to switched power so thats why when the car is off the wheels turn. BUT...when i start the car and press the brakes then put it in gear guess what ](*,).
I appreciate everyone's input but this one comes down to me not thinking
