How do you prepare for toilet training?

Let child dictate: Children often begin to show interest in the bathroom between ages 2 and 3. Girls often times earlier than boys. When this happens make sure you talk about the bathroom, even bringing them in with you. Buy a small potty if you want and allow them to sit on it (its ok if their clothes are still on) to "practice." don't force it, just go with the flow and make it fun. Reward systems can be good.

Prepare?: Don't try to toilet train before your child is ready to toilet train. That is my best advice. Successful toilet training depends on waiting until your child wants to train. Most typically, this is after 2 years old and before the 3rd birthday. Introduce the concept to your toddler. Think about some trivial reward system. Don't get angry about mistakes. The parent needs to be prepared most.

A toddler who walks: from room to room, pulls his/her pants & pull-up or underpants up & down & says " pee-pee", "poo-poo" or "potty" to indicate he senses the urge to "go" is ready for daytime toilet training. If not, you may create a behavior problem . There's no harm in putting a potty chair in the bathroom for the child to sit on while you model using the toilet, but don't force the child to sit on it.

How to toilet train: It's good to start early (app 2-21/2+ years old) without causing pressure. The child should start by simpling practicing sitting without the expectation of producing at least 2-3 times per day. The child should receive a reward or sticker for sitting. The time should be fun, not stressful.
