Thank you all.

Santosha, Thanks for the checklist. I had seen it before, several months ago, when her her behaviour wasn't so bad.
Out of the first list I would tick 4 out of 11 behaviours and in the second list I'd tick 10 out of 17.
Luckily she is always very gentle with other children. Phew!
I guess I could see an Occupational Therapist.... Does anyone know if you need a doctor's referral for them?? I am in W.A.

MadB thank you, I have heard of Failsafe & Fed Up and am happy to try anything. Will investigate.

Thanks LimeSlice for your suggestions. That is what I am hoping for - that she is normal, just active! Maybe I find it hard to deal with because I am the exact opposite! I'm a quiet person and I was a very, very quiet and inactive child. My mum was overly protective so I didn't really go outside or to parks, or even run around outside! (Luckily I was naturally stick-thin, but still not good to be so inactive!) The first time I ever ran was in year 1 at school
When we visit my parents, they have absolutely NO idea what to do with her. This is partly because they are old-fashioned (they are in their 70s but are extremely old-fashioned). My mum constantly comments that she "acts like a boy" (whatever that means). Luckily for them, all of their kids had sedate temperaments and spent their childhoods sitting around the house Anyway, I am getting off topic.

She does have a trampoline but only uses it sporadically - she prefers the couch! We have a small backyard but we use it as much as we can.
She did go to a dance class but we stopped... I should look into something for next year. I think she will benefit a lot from pre-kindy next year.
