Your baby is beautiful! I know how worried you must be. My daughter, who is now almost 7 had a large hemangioma in the center of her forehead. She had surgery at 13 months. Propranolol was not a known option at the time we were going through this so I can not speak to that but I can say we have now regrets about our decision and are so happy with the results.
I have attached a picture here from her first birthday, about five weeks prior to surgery. For some reason I can only attach one photo at a time so I will attach a more current photo in a separate post so you can see what she looks like now.
Good luck with your sweet baby!
