How old is your son Lylah?
My daughter also had this problem during the first 5 months of her life. Personally, I think it's due to the weather condition in HK - being humid and polluted, but there's nothing much we can do about that, can't we? Try to dress him lightly, lower your aircon temperature (basically just avoid him to sweat), bathe him in room temperature (not warm water).
I took my daughter to half a dozen of paedi and dermatologist. Depends on how desperate you are for the medication. Desperate, they'll give you hidrocortisone cream. Not very desperate, I've been explained over and over and over that some children (usually born to allergic parent) have high skin sensitivy. One dermatologist put it this way: it takes an elephant to break our alarm system, but these children, an ant is enough. I hope you understand

And I was also told that it would go away as they grow. Of course, at that time, I refused to except this explanation, but that's the fact....
My daughter got over her eczema, when we took her to Europe for holiday, thus temperature was lower and pollution likewise. She's 4 now and still get eczema evry now and then, especially during summer (when she sweats). I always keep the air con temperature at about 22-24C for her. Even in her bed room.
I hope my explanation can give you another insight of the problem your son is having!
Good Luck!

I would appreaciate recommendation for good baby dermatologists in HK side.
My son appears to have all the signs of baby eczema and while I have been following home care tips like baby detergent, non-perfumed baby bath, cotton clothes etc, the skin rash doesn't seem to be getting any better and so I want for a specialist to see him already.
Thanks!
