Opening the door

Anyone that is a parent of a toddler can totally relate to this. How annoying is it when they learn to open and close the door? Jordan is obsessed!!! I look away for .5 seconds and he is behind a closed door, usually his room. In the morning while I get ready for work I have to stand against the door to keep him from shutting me in it and then oh bring on the fits.
Ok that was my rant on opening and closing the doors- Up next when he learns what the doorknob does...
