what does your LO do?
I contain my one year old in the living room but my oldest either barges in and announces that SHE needs to go, RIGHT NOW.
or she sits outside the door reenacting Frozen (*knock knock* do you want to build a snowman? it doesn't have to be a snowman.. 'Go away, Anna!" ")
my husband just went in and locked the door and I sat here gleefully waiting...sure enough, she has to use the potty RIGHT NOW and has been banging down the door. "I have to go to the potty!! why are you in so long?! why you lock the door?!" haaaaaaa. he has no idea.
