Per my bb's case, use doctor's given 類固醇cream control the situation sin. Once under control (normal after 1 to 2 times thin layer 類固醇cream) then with oil bath, and continuous cream; bb's skin would resume ok ga la. But remember need to keep clean and cream on all the time; otherwise once gets dry, it will itchy again ga la (slaver on face will turn red and itchy).
Now my bb 4 and a half mths old, he was so itchy on the head and scratch so much into all wounds as well in the last 3 wks. Doctor said don't use shampoo to wash the hair anymore as the weather getting dry. And since last wk i started to use QV bath oil and QV cream for my son; the case turns much better.
Cream has to continuously put on face and head (especially the dry areas), he then would stop and reduce the scratching ga la.
