These are some of this signs that your child may be ready for toilet training: understanding the words used with toileting, understanding how to use the potty and even wanting to sit on it, asking to be changed frequently, and trying to hold it some. When they ask to be changed, don't necessarily drop everything. Tell them you'll do it as soon as you can. The sensation of a dirty or wet diaper can reinforce independent toileting. They may have dry diapers for longer periods and may go behind the furniture for privacy.
Make it a pleasant experience, not one they'll want to avoid. As they show positive signs and efforts, be sure to encourage and praise repeatedly. Give rewards for success and never punish or reprimand. Let them believe they are in control. Toileting happens before you know it, usually sooner rather than later.
