When babies are 4-6 months old, they are in the teething stage. At this time, their mouths produce a lot of saliva and are most likely to become inflamed due to drool rash. The symptoms of drool rash are similar to those of eczema in that they are dry, cracked, itchy, red and swollen, with small blisters appearing, which can cause bacterial infections when scratched and then oozing out tissue fluid. Therefore, to distinguish whether a baby has inflammation due to drool rash or eczema, the biggest difference lies in the location of the inflammation. The main areas of drool rash are concentrated in the areas where the baby gets saliva easily, such as around the lips or jaw where the inflammation is most obvious. If parents notice a rash near the baby’s lips during a period when they are prone to drooling, it is likely to be drool rash. However, if the baby often sleeps prone and drool gets on his face, his cheeks may also get a rash. Eczema, on the other hand, is most often caused by allergies and can be easily distinguished by a rash that appears on the trunk and extremities, rather than being confined to the face. In order to prevent the occurrence of drool rash, parents in the baby teething period to wipe away his saliva at any time, do not wipe hard, gently wipe the saliva dry to avoid damage to the local skin. The handkerchiefs used to wipe the baby’s saliva should be soft and cotton, and should be washed and dried frequently to keep them clean and hygienic. If your baby has grown drool rash, you can try using sesame oil or sesame oil to your baby, and then apply eczema ointment or gentamycin, erythromycin ophthalmic ointment to protect the local skin and prevent inflammation.
