It never happens with the girl baby. But it happens to 40% of baby boys. It's the acne. It happens because of the residual maternal hormone inside the baby. It happens during the 2nd week after birth and might continue for a month or up to 6 months.
We were taking the baby for weekly check up because the baby had lost some weight when we left the hospital. When the doctor noticed the blemishes on the face, he told us that it's the acne and it would go away. Nothing much should be done to those blemishes.
But over the week days, we saw those things growing and spreading all over the face and into the head and on the forehead I could see pus formation. But we had no clue about acne and we thought that's how the behavior of acne is.
When we went back to the doctor for the next weekly visit, he got worried about the whole acne thing. It was not acne at all. It might be Seborrhea(Seborrheic Dermatitis) or otherwise know as Cradle Cap. Doctor also didn't rule out some type of bacterial infection.
He took some pus for culturing the bacteria to know more about it and immediately prescribed an anti-bacterial cream and hydrocortizine cream to put on the baby alternatively. If it's an bacterial infection than the anti-bacterial cream would take care of it and if it is Seborrhea, the hydrocortizine cream would take care of it. And he told us that in 2-3 days he would call us to tell us about the bacteria culture result.
On applying both the creams, the infection started going away. But it made his cheek skin rough. We could not put any lotion on the cheeks to make it soft. In three days every thing vanished and the skin got back its baby glow. We were very worried at the beginning about the marks staying back. But thankfully, it didn't. But we still didn't know whether it was because of the bacteria or Seborrhea.
Finally, the doctor called and told us that it was a bacterial infection and continue to apply the anti-bacterial cream; discontinue using the hydrocortizine cream.
Now we are still wondering what type of bacterial infection could have happened and how? We have no clue about it still now!
