Last summer, Raylan Sonnenberg appeared to be the epitome of a happy, healthy toddler. He had hardly known a speck of illness and was already walking around his Plato home by the time he was 14 months old.
“He was very healthy,” said his mother, Lisa Sonnenberg. “But then, by the time he was about 16 months old, we began to notice that he was not walking as well. He was falling over more and using a wider stance.”
