hi, my 20 month old grandson, has severe flat head, my daughter has been told at 20 months old it is to late to do anything, my daughter is really upset, as the doctor told her months ago that it was not to bad, but a private clinic today told her it is very severe, his ears are not aligned as well, they can try a helmet, but the prognosis is not great, after 14 months , has anyone had any results with a helmet at 20 months old
