What is the reason for the redness and swelling of the baby's penis?

Patient's question:

No

Doctor's answer:

Pay attention to letting the child drink more water regularly. Tell the child to urinate until it's clean before pulling up their pants. Clean the little penis of the child every day. If drinking more water doesn't help, then use potassium permanganate for washing. Be careful not to put too much, just a few grains are enough. Apply gentamicin eye ointment.
