My baby face also had rash on face when he was 1mth..
it should be caused by milk.. u should go to c doctor...the doctor may give u cream..around 2-3weeks..the situation
will be improved...but the rash will come and go..so u
have to pay more attention on the cleaning procedures..
u may use warm drinking water wif cotton
to clean baby's face at least 2 per day..then after every
meau..u also have to use warm drinking water
and cotton to clean baby's mouth and the surface
around the mouth..
