Thanks Heather. I suspect his case isn't too severe but I guess we'll know more as he gets older. He still doesn't have good neck or trunk control and his muscles in his arms and legs are tight many times. He's basically has the control you'd expect from a 4-6 mo. old in a 9 mo. old body. The docs say that with physical and occupational therapy, he will improve, but they don't know how much.
