M.M.
is she ready to potty train? my son went thru a similar phase but he was younger. i put him in one piece PJ's for both nap and nighttime. If he did it when we were awake I didn't make a big deal about it. I just told him no, we don't touch poopies it's dirty and yucky and cleaned him. I didn't yell at him for it. At that age they are exploring - gross or not. If she isn't ready for potty training yet I'd just keep a close eye on her. it will pass.
