Can you tell me how i could potty train my 3 year old?

A pre-schooler who: walks from room to room, pulls his pants & pull-up or underpants down, says " pee-pee", "poo-poo" or "potty" to indicate he senses the urge to "go" is ready for daytime toilet training. Use a potty chair or Little Looster for stability. First step: When he starts to poop, calmly walk him into the bathroom, keep on his diaper, let him empty it into the toilet & flush it. Reward each step.
