Weird red blotches on babies face for a minute when he starts eating?

I've been noticing sometimes when my son starts a bottle he gets all blotchy!! It only lasts for a minute literally. Ive googled it and it seems to,happen to other babies too. It said its increased blood flow in the face from him sucking? Especially in fair skinned babies. Anyone else's baby do this? First eating, one minute later its gone
