What To Be Done For The Red Spots On My Children S Forehead?

Hi,My two children were born with red spots in their fore head, the doctor told me that it was due to the pressure cause by gong through the birth chanel. They are 4 y 6 years ole now and still got it, and is more obvious when they are hot or running, looks like a bit scratch right in the middle. When my son was young he use to vomit a lot and shake but nurse told me was coz he was hungry, the shaking stopes but the vomit didn t till he was 1 and a half old. His head has a strange form ( like dad) and his front head is big, my doughter has a flat head. Should I worry?
