The diagnosis of benign congenital hypotonia (BCH) is now a controversial one.[1] Since the first description in 1956 it has been possible to diagnose children more accurately who would otherwise have received this diagnosis.[2]
However, the term 'benign congenital hypotonia' is still used to describe children with mild hypotonia who appear to have a favourable outcome and in whom no other diagnosis can at this stage be made.
