Get any help you can. I understand you fully and we've been in the exact situation multiple times. 
I can not talk for your child but I know my daughter can catch me easily if I watch her tics and this makes her nervous and also negatively effects the tic frequency. I still get caught time to time, but I thought myself to make her comfortable during the peaks as it's the not the easiest but shortest way out for both of us.
I think stress certainly has an effect. Under negative stress I see the tics rise quickly. I try to apply positive stress as much as possible, like a physical competition , memory games, any thing that would direct her concentration to somewhere else. 
Believe it or not, every 30 sec is not really a high frequency. I had so much worse on some tics. 
Just today, she started blinking both eyes same time (not like blinking but like closing and opening) , we had this tic couple of times before. Sometimes today it got really frequent. A few minutes after I told her, it might be better not to use iPad as her eyes look tired, she came and told me, I don't want to do it (close eyes) but I also want to ... trying to explain herself. I said, it's quite ok and to do whichever she feels better, closing or not closing and added it will go away in a few days maximum anyway (that's some good will) 
Back to my first sentence, get any help you can, if you are not well, you can not help. 

I have to agree with Madimi that tics, especially at early ages effect the parents far more than then the child. A long as it's not because of extra stress or anxiety, I don't very actively try to remove triggers anymore. ( I still sometime do selectively) i.e. My doughtier had a very certain tic when we were playing volleyball but I kept on practicing with her (she eventually got to a point she is better than me now) and that particular tic went away quickly. 
 
Btw, after a very steady decline we have seen an increase starting one week ago (we are at vacation , traveling new places ) not as bad as our 'worst' times, but still far worse than our average for the last two years. I hope that this temporary but I also know puberty may increase the symptoms. 
I really wish I could stop worrying.

Greeting from Dubai, I know how difficult it's, at least at the beginning. Tic disorders are a very wide spectrum and every child is wildly different though there are similar patterns shared among them. One thing that is very clear to me is, basic tic disorder is significantly common, I've seen it at several of my friends/relatives kids and if you think how uncommon it's among adults, you can understand that many of the kids will get to a point it's not easy to detect. 
There are several kinds of tics, but I think vocal/motor tics is a very bad way to categorize them, also meaningless. As many believe, I think Tourette Syndrome naming is not very meaningful. Coughing is an physical activity and unless your kids is doing it for the sound of it (very unlikely) it's more or less a motor tic. Our daughter also made some short noises like 'hih' when she had abdomen related tics. I did not consider them as vocal tics.
As I pointed out in earlier posts I found that my kid had less tics when she felt more confident and I focused adding her skills that would make here feel confident of herself when under pressure. It's impossible to know exactly if that helped or not, but I don't think it caused any harm. 
Don't worry tics will wax and wane, peak points will start getting lower and lower after one year usually and every following year it seems to get better in our case. Do we have tics, yes, but to a point that I usually not notice them. But we still have some peak periods after four years and I repeat my self to hold on 1-2 weeks... 
 

We still have some tics here and there, but they are getting increasingly difficult to detect even by me. There still moments where tics do increase , but it's relatively a lot easier peak and relative to the first two years peaks duration is significantly shorter. 

Hi, 
We are doing ok, we still have 3-4 tics with wax and wane. In the long run we think we are in a descending trend. 
Please do not consider me an authority. I am just an other worried parent. 
Unfortunately there are way too many unknowns about tic (and related) disorders. There are very few researches that focus on underlaying reason for tics and why some get better and others don't. Luckily there are now, some researches on the topic like EMTICS and some other I pointed out in other posts.  
I try to stick with evidence based treatment strategies but this does not mean that others methods can not work. Tics wax and wayne and expected trend from onset is downwards. This makes 'isolating' the effects of supplemental vitamins/diatery changes and other things very hard. 
We try to follow a healthy diet with no MC Donals or smilar stuff. We tried 'gluten free' diet for a while and also a 'milk' free one. It was quite hard for us. At the end we gave up but still limit 'milk' as our doctor told us that he does not think these have any relations with tics but reducing milk is considered healthy anyway and won't make harm. 
I am not knowledgable on mercury poisoning enough to comment on it. Mold is unhealthy and so there is no harm getting rid of it. I use dehumidifiers time to time to prevent mold as I am practically living on an island. 
For the naturopathic DR, I only believe in evidence based medicine/treatment , if the DR can point to some research results about why he is making the tests etc, I'd check , otherwise skip. But that's me. 
I know how 2 months feels like multiple years under stress, been there. I remember that I lost 20 lbs in the first 3 months very rapidly. However when it comes to tics, it's a very short period. 
Can some movements be other things then tics? Yes, they can be. Some hyperkinetic movements can easily be misdiagnosed as tics. (or there is a type of seizure which often looks like a tic.) Here is a paper on the topic you may find interesting. 
https://pubmed.ncbi.nlm.nih.gov/9613740/
Also compulsions, impulse behaviors etc can be misdiagnosed as tics too (does not like your case though) , you can read an old paper on the topic here, a google search may find newer ones. 
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2656307/
I believe in the thesis that Tics, OCD, Hyperactivity etc.. are different manifestations of the same underlaying condition. 
I also read that tics being elastic is considered a good thing, on the other hand I think it's actually the norm. Tics keep changing, usually in 6-12 week periods. But some stick longer, some stick shorter some come and go changing a bit every time. 
While not useful much, I also observed that sensory physical stimulation does trigger tics. As an example, using googles at the pool, after some period of time would start triggering 'eye' related tics. Teeth development (new teeth coming etc..) can trigger tics around jaw. 
I believe relieving anxiety and supporting self esteem should be the focus. I support her to gain new skills as much as possible to up her self esteem. We had the same issue with gymnastics and continued online. Not 100% effective but 80% was ok. She got quite strong so she does not feel under stress when physically challenged. 
Btw you are as important as your kid and you also need to find ways to keep your anxiety levels low and manageable. It will build up and it can result in behavior that will result in increased anxiety in the child. (been there , done that) 
Keep on updating us 
PS: Intensity of the movement (speed, extension, strength behind) etc is also a good measure like frequency and can give you insight on the trend. I think we've seen noticeable decline after 4-5 months or a bit more. 
best regards
Mertol 
 

Here comes an other update. 
I started following tics on an excellent sheet that helps me figure out progress of tics and when they emerge and when they get out of the picture. 
At the very first 2 months after 'new' noticeable tics kicked in we had some ups and downs however they never got very bad or to a point that would effect her social life. At the 8th week a steady decline started and leg/arm jerking slowly decreased in intensity and frequency and now gone. However during the course a few more tics came and go. We had some head nodding that was very infrequent for 5 weeks , we had a jaw opening tics that was also very infrequent for 8 weeks , a hip related tic that was frequent when walking but went away in a few weeks. 
Interestingly some long standing tics are gone now too , like broadening nostrils and nose twitching (not sure this was tics or related to allergic rhinitis) are either gone or very very infrequent that I do not notice. 
On the other hand an abdomen tic (that is pretty easy to mistaken for a breathing tic ) is back. It's not frequent and very hard to recognize externally so that does not worry me as much. 
EMTICS have published several papers , so if you've not read them those can be good resources. 
We are not using any supplements other then the very usual stuff. We are still focused on 'positive stress' , less TV/Phone'Tablet time , more physical activity. I think that being confident really helps her a lot and at her age part of the confidence comes from her physical capabilities, so I feel like gymnastics really help her a lot. 
 

I personally think that hyper activity is an other form of a ‘tic’ , an urge to do something, so might be considered part of the spectrum. That’s my personal opinion yet prof I chatted on the topic agreed the view. 
 
We had the same issue of tics before sleeping for a long while, almost a year. 
 
Make sure you got all the help you can to cope with the situation. 
 
i am positive that you will be in a lot better situation in short time.
