Well i have 3 year old twin girls and a 1 year old baby girl. I said from the first they will use the potty by 3. So what i did was let them run around the house naked and when they hd to use the potty they would go. I had potty chairs all over the house. Then we went to panties and by 3 they just started going to the potty. I never made them go or sa we were learning to use the potty they just did it on their own. Another thing you can do is get potty candy. My friend put some in a covered jar on the back of the big potty and her little girl would get just one everytime she used the potty. Oh i also gave mine gum when they went only because they thought it was something special. Good luck!
