Does baby daughter with clubbed feet, clinched fists, small size haveserious condition?

POTENTIALLY YES. Clubbed feet on its own and without any other associated dysmorphic features, does not have any serious implications, but when associated with other features, i.E clinched fist (beyond 6-12 months old) , small for gestational age, microcephaly(small head) etc. Should be a cause for concern, thus requires evaluation, both by a geneticist and neurologist.
