Potty training is a significant milestone in a child's development, and every parent wonders when is the best age to start. While there is no one-size-fits-all answer, experts suggest that between 18 to 24 months is the ideal time to begin. However, each child is different, and readiness signs like showing interest in the toilet, staying dry for a few hours, and communicating their needs can help determine if they're ready. Avoid pushing your child too early, and remember that accidents will happen. With patience, consistency, and positive reinforcement, your child will eventually master this skill and make the transition from diapers to underwear.
