Parents often complain that after their children wear diapers, skin eruptions on the buttocks are always bad, and even the anus is almost rotten. What exactly does diaper rash look like? Diaper rash does not look exactly the same. But if the area where your baby is wearing a diaper looks red and uncomfortable, it’s a sign that he may have diaper rash. Your baby’s skin may also be a little swollen and warm. Your baby’s diaper rash may not be serious, just a few red spots in a very small area, or it may be more serious, with painful bumps that hurt when you touch them and spread to the tummy and thighs. But you don’t have to rush: dealing with diaper rash will be a regular thing, especially until your baby is 1 year old. Causes of diaper rash 1. Untimely diaper changes Babies absorb quickly and excrete quickly. Small babies need to urinate about 10 to 14 times a day, each time after wetting, if the diaper is not replaced in time, it will lead to the skin of the baby’s buttocks for a long time in a humid, stuffy environment that is not breathable, thus forming a diaper rash. 2, improper cleaning of small butts Some new mothers do not clean their babies’ small butts in time due to inexperience, while some mothers clean excessively and destroy the natural sebum protective film on their babies’ small butts, leading to some bacteria and dirt to take advantage of. 3.Physiological diarrhea or breast milk diarrhea Some babies have diarrhea due to lactose intolerance or various reasons, and the irritants in the feces and urine will also make the little butt red. 4, allergies Because some babies are allergic, and some mothers use diapers with more chemical fiber components for their babies, or often use some cleaning solutions, wipes and other items that contain stimulating ingredients, resulting in skin allergies on the baby’s small butt, which is also one of the reasons for red farts.
