Hi. My 5 year old had a coughing tic for almost two months which eventually went away (I told him each time he feels like he needs to cough, take a sip of water and within three days it was gone). He also gets very overstimulated easily. He was sensitive to noise but social, sweet, smart and kind. I use past tense because most of it is gone. A lot of it was going on between 3-4 years. I will say I put him in Kung Fu and it has done wonders for self control, overstimulation and impulsivity. In addition, when I was little I had tics- squinted, rocked, etc. I grew out of it by the time I was in about fifth grade and am fine today (although My husband may disagree:-). I would not worry too much.
