Hello Derek,
I am not a doctor but a parent. Sorry, but your doctor is DEAD WRONG. NO scoliosis does not fix itself. Our daughter is a prime example of that. It MUST be treated early and it must be treated properly.
Seek out the BEST doctor, the highest respected doctor for infant scoliosis. You want an expert who will know the very best way to treat your precious young daughter.
Wish your daughter and you as her parent the very best.
