Hi V. In my opinion at 20 months old she would do better in a home daycare than school type like daycare. I start potty training my daycare kids at 20 months as I did my own 3. Diapers and or pullups will hinder her, because it is confusing to children when it's ok to poop or pee on your self at night or other times, but during the day you use the potty. I never use diapers or pull ups during potty training whats so ever, I also make sure that the parents are on the same page with me, so the same rules apply here as to at home, in your situation the daycare needs to be on the same page with you, since you take her to them, it's not fair, and it is very confusing to do things one way at home and one way at daycare. I have been potty training other peoples children for 13 years, 90% of them before or by 2. I don't see how taking your child to the potty put other kids in danger, it sounds to me they just don't want to deal with it. You may have to put her somewhere that will work with her, cause honestly Susan, if only you are working on it, it defeats the purpose, and it's not fair to your daughter. You may get many moms telling you 20 months is to soon, please don't listen to them, I have much experience in potty training, and I have found that starting children early is more effective. Please do not take Christina's advice she is intitled to her opinion, but how much experience is it bassed on? J.
