A few questions to ask yourself before you begin potty training:
Are YOU ready for potty training or is your CHILD ready for potty training? You'll get the best results if it is your child who initiates the process.
Does your child 'know' when he or she has to urinate or have a bowel movement? Does he or she articulate that in some way BEFORE it is about to happen? If so, your child may be ready.
Does your child come to you and tell you that he or she has a wet or poopy diaper? Does he or she go into a corner or another room for some privacy while urinating or having a bowel movement in the diaper? If so, your child may be ready.
Good luck with potty training. Remember, it should be about the child being ready! We've used Potty Training for Dummies, the "Go Potty, Go!" video, and have had potty chairs available for our son.
