My eldest DD had a big raised one on her big toe, and another smaller one above her right breast, and our paed told us they would fade in time and they did, with no troubles at all. Some will continue to grow for a while as the child grows, but then they will get smaller and dissappear. It wasn't till she was nearly 1 that they were completely gone though. Unless they continue to grow and cause a problem with breathing/feeding etc, it should be fine, albeit a little unsightly.
