My DD has been using the potty since 9 months old. She loves sitting on it and playing and by now, at 19 months old, I can tell she know what it is for. However, despite being very verbal, she does not tell me when she has to go. I have had 2 very long days of attempting going diaperless (a month apart from each other). She will pee when standing right next to the potty. She also seems to pee a lot, like sometime 2 or 3 times in the same hour. I would swear she is ready, but I don't know how to get her to communicate she has to go beforehand. She will tell me right after she's gone, "diaper change" and even go and get the new diaper. Advice?
