Children attending daycare do just as well at toilet training as kids being cared for at home.
The study found that on average that toilet training took eight to ten months. The average age for toilet training success for girls was 35 months and for boys 39 months. There was no explanation as to why black parents toilet trained their children earlier than white parents. Black children typically began potty training at 21 months and finished at 30 months, while white children began at 29.5 months and finished at 39 months. Parents should start the training when a child begins staying dry during a nap, showing interest in the bathroom and following simple directions.
