The anal desire stage is commonly seen in the childhood stage, and will be characterized by holding stools, changes in bowel rhythms, and changes in urination rhythms. 1. Holding back stools: When children enter the anal desire stage, they will appear to hold back stools while playing with toys. At this time the child is looking for the tipping point of not being able to hold it in. During this period, young children mainly obtain pleasure through the retention and discharge of feces. 2. Changes in bowel rhythms: Before the onset of the anal desire stage, children may have a bowel movement once a day. During the anal desire stage, there are usually two bowel movements a day or one in two days, and after the onset of the anal desire stage, the bowel rhythms return to normal. 3. Changes in urinary rhythm: During the anogenital phase, the child will experience contraction and dilation of the urethral sphincter over and over again on his or her own. This is when the child is learning how to control the sphincter and frequent urination occurs. It is recommended that children who develop the anal desire stage may also have other symptoms, and that parents provide timely psychological guidance, and can also be corrected under the guidance of a counselor, so as to avoid psychological effects in adulthood.
