Withdrawal emergent syndrome (WES) is a subtype of tardive dyskinesia that has been reported in children who were taken off antipsychotic therapy. We present the first case of WES in an infant born to a mother taking haloperidol during her pregnancy. The infant developed repeated tongue thrust, abnormal hand posturing, and tremor of all extremities. Most symptoms resolved within several days, but tongue thrust continued until 6 months of age.
