My granddaughter is 10 months today and has hypotonia. She has been preliminarily diagnosed with a Chromosome 4 disorder, but we have no additional specific information yet. The parents are being tested soon to determine if the Chromosome 4 issue was inherited. In addition to the hypotonia, Megan has low set ears, a pronounced jawline and chin and her eyes do not always coordinate. We have been working with her through early interventionists and that seems to be helping. My questions are, if the Chromosome 4 issue is minor, will early intervention be successful in Megan s ultimate development by a certain age? And, are there are any supplements that would aid in decreasing her hypotonia and assisting in her development? We need some hope. Thanks for your input. Tania.
