I think I'm one of the few that wanted their kid on steroids earlier - I was searching for a doctor to prescribe steroids when my youngest was only a few weeks old, but didn't find a doctor willing to do so until she was 2 months old. I would have preferred a steroid injection - just because it is easier than giving the child liquid medication every day - but no one around here was willing to do so (too close to the eye). She was on oral steroids from 2 months to 5.5 months, first at a dose of 2.8 mg/kg, then increased to 4.2 mg/kg, because the hemangiomas were still growing at the lower dose. She later had a steroid injection at 7.5 months (in CA, we are in PA).
While the steroids did not shrink her hemangiomas, they did temporarily halt the growth. She had the puffy cheeks, but otherwise was fine. Her growth in height was stunted for a very brief time, and the weight - well, we're still working on the weight gain, but all 3 kids are lightweights anyway.
I personally would try the steroids if the hemangioma is growing rapidly. Good luck with whatever you decide to do.
