The control system for babies' urination and defecation is mainly the nervous system. With good neural development, babies can actively express their need for urination and defecation, or directly solve it themselves. But if the baby plays too much, it is inevitable that they will urinate in their pants. So, at what age will the baby defecate and urinate on their own?
Generally, around the age of two, the development of the central nervous system in babies is relatively complete, allowing for better control of urination and defecation. Babies may have a desire to urinate or defecate independently, but at this time, they may also neglect and dirty their pants due to urination and defecation. When a baby can urinate and defecate on their own, it is not until after the age of three that the neural development for controlling urination and defecation is sufficiently complete. All that is needed is to prepare a bedpan for the baby.
After the baby can walk independently, it is necessary to train the baby's ability to urinate and defecate on their own. Mothers can prepare a toilet bowl or toilet seat for the baby to facilitate their use of the toilet and avoid dirtying their pants during urination and defecation. At the beginning, babies will be more interested and will imitate the way their mothers go to the bathroom. They will also gradually develop the habit of consciously going to the bathroom when they have a need for urination and defecation.
During the process of practicing, babies may inevitably forget. At this time, the mother should not scold the baby loudly, which can cause pressure on the baby's urination and even lead to incontinence.
