Diaper dermatitis, commonly known as red bottom syndrome, refers to the redness, red rash, moistness and erosion of the skin on an infant’s buttocks. The vast majority of red bottoms are caused by improper care, and only a few are due to allergies to diaper materials. The mechanism of occurrence: Untimely diaper replacement and the use of poor quality diapers with poor breathability make the baby’s buttocks damp and stuffy for a long time, which, together with the stimulation of ammonia in urine and feces, eventually leads to red buttocks. So, if your baby has red buttocks, the first thing parents should do is to review whether they have given their baby a diligent diaper. Mild red buttocks can heal themselves as long as you change diapers regularly and pay attention to keeping the buttocks clean and dry, but serious red buttocks can lead to skin erosion on the buttocks and combined bacterial and fungal infections, which require careful care and treatment. Like all diseases, the focus of red buttocks is on prevention. When it happens, one is the baby’s pain, the other is the parents’ sadness, and the third is the need to spend money on treatment.
