1. Buy supplies. A potty chair (floor level type), stickers or stars for rewards, underwear.
2. Make the potty chair one of your child's favorite possessions. Take them with you to purchase the chair, encourage them to decorate it or put their name on it , encourage them to sit on it (fully clothed). After about a week you can proceed with toilet training.
3. Encourage practice runs on the potty. When your child is giving a "signal", grunting, grabbing genital area, squirming, squatting or after naps and meals. If your child wants to get up after one minute of encouragement, let him get up. Even if your child seems to be enjoying sitting there, each session should stop after five minutes unless something is happening.
4. Praise or reward your child for cooperation or any success. Cooperation with practice sessions should be praised. If your child actually uses the potty, treats or stickers as well as praise and hugs should be given. Big rewards should be saved for when the child goes in on his own and uses the potty. Practice runs and reminders should not be necessary for more than one to two months.
5. Change your child after accidents. Tell them they'll get better at this. Avoid physical punishment, yelling or scolding.
6. Introduce training pants after your child is using the potty. Usually when they are passing half of their urine or bowel movements in the potty is a good time to switch. Underwear can be a reward. Buy loose fitting ones so they are easy to pull up and down. Once you start using training pants, only use diapers at night and for naps.
