Is this tourettes?

Hello,

So a long story as short as possible. My wife and I have 3 girls. Our middle girl (P, age 4) has been seeing doctors a bit over the past year because she has a night time rhythmic movement disorder but we've just been discharged being told that it's not effecting her development and she should grow out of it. The doctor just so happened to be a child behaviour specialist and we got on to talking about our eldest girl (Izzy, age 6). Izzy has had a few tics for at least 2 years now, she's been sniffing and clearing her throat the longest, probably the whole 2 years but also does some squeaking more recently and used to do wide eye opening (is the only thing I could call it) but in the last 6 months or so it's changed to more like eye rolling, she kind of looks left and right, I'm sure you all know. Originally we thought all the throat clearing etc was her allergies as she's allergic to cats, but we don't have pets and since mentioning to the doctor about her tics she said gave us a leaflet on tourettes and cold us to contact our GP to get referred to a specialist.

*Mod edit*

Does this look like it is what we now think it could be?

Thanks. J

We just took Izzy to the opticians today and he said her eye movements could be to do with her eyes being strained. He said she's long sighted and should wear glasses for watching TV, iPad and reading etc.

I'm still not convinced it's anything to do with that because she does it all the time. Even just walking around...
