Encouraging practice will help your child learn the basic potty skills. In addition, you will want to make sure your child eats lots of fresh fruit and vegetables. Prune and apple juice are always good staples to have around when BM training. You want to keep your child's stools soft to prevent withholding of stools. This will help build self-esteem.
Timing is an important factor in toilet training.
Remember, encourage and guide, but do not force your child to sit. No big deal, try again in a month or so. Let your child take the lead. Your child needs to be in control of the process. If your child has a painful BM only once while trying the potty, it could delay potty training for months.
