I'm in Sydney so can't help at all, but just wanted to say I think it's a great idea to have him checked out! A friend of mine lost her little brother to SIDS so has to have all her babies taken in for sleep studies and has just found out that her 10 week old baby girl has quite a severe case of sleep apnea.

I'd maybe contact your local children's hospital, that's where my friend has taken her kids to have the sleep studies done.

Good luck!
