Time for consultatn: It is time that the kid had a full physical and developmental evaluation.This can start with your pcp but may need the services of a developmental pediatrician, pediatric neurologist, speech and language specialist, and occupational therapist. A loss of communication skills after acquired is worrisome.The causes are varied, but a workup can sort most kids out and define their needs.
