I decided to buy Ella some underwear (or “unders” as she calls them) to wear around home the days she feels like sitting on the potty. I chose some with Elmo on them. I brought them home and showed them to Ella and she decided since they have Elmo on them they must be for Elmo. So she puts a pair on her Elmo. I just know where I am going to find some underwear with a picture of Ella on them for Ella. 🙂
