My baby still hVe red vessels mark on his forehead ... he is around 4 months.. what is that mark means??

A. Hello good afternoon !! It doesn't seems like red vessel better consult with Paeditrician. Is it appearing since birth or these days only. Check if baby hitting any wall or anything while rolling over or applied any bindi unsuitable bindi or kajal also leaves mark. Apply coconut oil before bath morning and evening and leave for 10 minutes .
