Is your child displaying frequent eye-blinks, shoulder shrugs, sniffing noises, or other repetitive movements or sounds? If so, your child might have tics. Tics are sudden, recurrent, non–rhythmic movements or vocalizations. They usually emerge between the ages of 4-6 years and generally affect males more often than females. Tics are often preceded by “premonitory urges”; unpleasant somatic sensations that typically occur in the area of the body involving the tic.
