Potty Training

We are in the thick of potty training, and just when I think that Mia's got it, she pees or poops in her pants. Yesterday, she wore regular underwear all morning, going pee pee on the potty three times successfully. In the early afternoon, my hopes were dashed when I smelled something stinky...poop! In the underwear! Ewwww. Today, she peed twice in the potty, and as of ten minutes ago, she peed in her pants. Total bummer.
