(HealthDay News) -- It's important to start potty training at the right time -- not before your child is ready.

The American Academy of Family Physicians says these signs indicate your child is ready for potty training, if he or she:

• Indicates a dirty diaper.
• Shows an interest in using the potty.
• Understands and follows simple instructions.
• Is uncomfortable in a dirty diaper.
• Can go at least two hours during the day with a dry diaper.
• Wakes from a nap with a dry diaper.
• Can pull pants up and down.
