Because the urethral sphincter, the anal sphincter, is not physically mature in infants and young children, feces and urine fart can not hold will automatically empty it.Generally speaking, wait until the baby one and a half years old ~ two and a half years old or so, will gradually enhance the control of urination and defecation.At this time, parents to the baby's toilet training, will be about 4 years old or so off the diaper.

When the baby can't perceive the feeling of urination and defecation, this kind of potty training will not only have no effect, but will prolong the time of leaving the diaper.According to the study, potty training for children under 18 months of age led to complete withdrawal from diapers by age 4, and potty training for children between 18 months and 24 months of age led to complete withdrawal from diapers by age 3.

Of course, the baby should pull. However, with the growth of the baby's monthly age and the improvement of various cognitive abilities, the baby will gradually strengthen the ability to control the urine and gradually learn to solve "personal problems" in the designated place when he finds the uncomfortable feeling of defecating in the diapers with the timely guidance of the parents.Conversely, parents' urination, to some extent, weakens the child's perception of being "pushed."If you succeed in urinating, it's not that the baby will go to the toilet, it's that you have mastered the baby's urine routine.
