Our soon to be 7 year old also has two tics, rapid eye blinking and blowing on her fingers. Her tics are not constant and only appear when she is anxious, nervous, or stressed.
She may go days, weeks, sometimes months without the tics. Then out of the blue they will appear again. When we see her starting to tic again then we know something is bothering her. It may be something as simple as learning new things at school that she may be struggling with.
We have been through a ton of testing including academic testing. Physically she is in perfect health but she is struggling emotionally. She is going into second grade this year. She tested in reading, comprehension, vocabulary, and critical thinking at an 8th grade level. Her math level is that of a 3rd to 4th grader yet she truly believes she is "stupid." (Her words not ours.)
Most academic things come extremely easy to her, however she struggles with the other side of her brain that controls things like fine motor skills. Writing, cutting, drawing, and coloring are extremely difficult for her. The doctors have told us this is all very typical with children like M.
It is also very common for those children to have anxiety disorders BECAUSE of the way their brain works. They expect to be perfect and their work should be perfect. This is a self imposed standard. When it is not what they deem to be perfect they get very frustrated and do not yet know how to deal with that frustration. She can not understand why most things come so easy for her but then the "simple" things are extremely difficult for her.
The inability to process her feelings is a huge contributor to her tics. The doctors and therapists have told us that most children outgrow the tics as they mature and are better capable of dealing with their emotions. None of the doctors we've seen have recommended medication for the tics. In fact they told us they normally do not medicate children this young because they usually outgrow them on their own. Unless of course the child's tics are so intense that they interfere with their normal life.
If you have not already done so, you may want to consider exploring possible emotional strains causing the tics. I would have never thought my then 5 y/o would have emotional or anxiety driven issues.
Peace and Blessings,
