Once your child is used to the potty, you can start to encourage use of it. This will help your child get the hang of using the potty. Also, remember to praise and offer a sticker for your child's chart for every successful potty use. Continue to read toilet learning books to encourage regular use of the potty. Keep the potty-chair out and your child will eventually show signs of interest again.
Timing is an important factor.
Toilet training can get messy, be prepared and expect there to be mistakes. Clean them without anger or negative comments. At night you can use diapers until your child wakes up a couple of days in a row dry.
