What is the best age for potty training?

There is no best age as each child have their own pace, never try to rush them .For me i started when she have learn walking , bringing her to toliet and try. When she learns to speak i ask her if she wants to go toliet everynow and then . Now at the age of 33 month,she is only wearing panties n pants at home and a potty that she like is place near the toliet. Praise and encourage her when she able to inform us that she wants to go toliet and remind her gentle if she forget and have wet her pants. Childcare also just started to go diaperless in school . Toliet training needs alot of patience and encouragment for the child . I bought many stickers to reward her too :)
