I've done that while watching 12 of my nieces and nephews. Before I took my shower I gave everyone a snack, locked the doors, turn cartoons on, and tell them not to go outside or answer the door and to get me if something happens.

yeah I leave the door between my bedroom and the bathroom cracked. it's just the only way I can keep her happy without seeing me.

I've done it before with my son, as long as they r happy and u can hear them it's ok
