Potty training a 3-year-old?

She needs a schedule. Have her go potty when she wakes up, 10 minutes after drinking something, after meals, and before bed. If needed you can put her in pull ups until she masters it because then its not as messy as undies. My sister is 3 and it was easy for her, and my other sister is 2 and she's DYING to pee in the the potty. Apparently what motivated me was that I saw my mom go potty and i wanted to be a big girl so i stopped wetting myself. But schedule, pull ups, and if she still doesn't stop, diapers and call her a baby. It irks them and makes them want to improve.
