How to deal with a red bottom for an eight-month-old baby?

Patient's question:

Very red, starting from October 25th

Doctor's answer:

Medical Analysis: Hello! The baby has a red bottom, which is diaper rash, mostly related to inadequate care. The child's blood count is slightly high, associated with inflammation. Anemia may be related to unbalanced nutrition in the diet.
Recommendations: It is recommended to ensure the child does not get cold while minimizing the tightness of the diaper. When cleaning the bottom, use water as much as possible. If using a cloth, avoid rubbing; instead, gently press and be very careful, as the baby's delicate skin is prone to tearing. If the child cries excessively without reason, check if the bottom skin is red—it indicates discomfort.
To prevent diaper rash, apply a layer of ointment, such as tetracycline ointment or eye ointment, after each cleaning. Also, change the diaper promptly and let the bottom air out to avoid the ammonia released during decomposition from irritating the delicate skin. In some cases, anti-inflammatory medication may be needed.
For anemia, further tests should be conducted to determine if it is iron-deficiency anemia. If so, iron supplements such as ferrous fumarate should be administered.
