we started my daughter around 4 weeks. she takes propranolol and uses timolol, which is topical. she has done just fine on both and we have seen big improvements already. she has large segmental hemangiomas on the side of her head and on her throat, so the chance of complications was pretty big if we didn't do something. she also has 2 that were starting on her lips and another below her left ear. i know it is scary, but from what i have read, most do just fine. good luck to you and let us know how things go!
