It may be better to bring your baby to see a paediatrician / child specialist doctor rather than trying to self-medicate. My baby's paediatrician prescribed some cream to apply and after a while the problem went away. The paediatrician also advised to use moisturizer at the same time as the cream and prescribed the moisturizer as well, which we cannot find from pharmacies.
Sometimes, we may also not know what exactly the issue is, whether it is eczema or some other skin disorder. The doctor can diagnose and tell you what is the best solution. And you can also ask for suggestions from the doctor as to what other products can be used. Usage of other products may aggravate the problem.
