So I have done the potty training business with my first after she turned 2, and it was surprisingly easy.... now my second daughter is almost 3 and a half! Nothing seems to be doing the trick ! Her doctor told me she is just playing with me and she knows what she is doing🙄 please someone help me... I'm very desperate 😂
