Hello can anyone tell me what this mark or patch looks like

[hope212]

Hi this mark or patch is on my bsbys head what could it be??

No idea on that one sorry. Have you found out yet?

It looks like a birth mark called a port wine stain.

My ds had a birth mark like that on his face.. Dr said it would be gone before he was a year old.
And it was.
Older ds's have a small one on the back of their necks. Faded but still visible close up..
