Hi Atex.
My son is 9 and his tics are also slowly progressing every year, but after obsessing for many years for finding triggers and going from one doctor to another, I recently decided to take a step back and just enjoy life. Every kid with tics is unique with his own triggers. Personally for me i don't believe change of diet, gut health etc.. made any difference for my son.
Cbit didn't help my son either, he even told his therapist; why i have to change my tics they dont bother me i just want to be free. This changed my view a lot my son isn't suffering from his tics only i was sadly.
Do i see triggers yes, screentime is a big trigger for my son, but i still let him, why take away something he enjoys just because he tics more while doing so! I see in the mornings he almost doesn't tic and towards the evening they tend to get more.
Exitment is also a trigger for my son we went to a Water park and he ticced more.
But there are also many times he doesn't tic at all. Like on the beach i rarely see him tic, where we spend many days cause we are living on a island. Or while eating dinner my son doesn't tic or when playing with his pet hamsters.
So what im trying to say we can help a little, but cannot control the tics entirely.
And maybe in a few years they be gone or maybe not.
But me being more relaxed helped my son for the better for sure.
Greetings
