Hi there! There a couple types of of congenital hemangioms, so it would depend on what type you were dealing with. There's RICH (rapidly involuting congenital hemangioma) and NICH (noninvoluting). I would recommend you email Dr. Levitin and send him a photo (go to the Ask the Experts link.) He can give you his opinion based on your son. Good luck!
