Missy, when CJ had his newborn hearing test at the hospital they gave me a booklet with a hotline for hearing... Called NSW Statewide Infant Screening Hearing Program - Information Line - 1800 551 175. Maybe they might be able to point you in the right direction.... Or else the booklet suggests getting a referral from your GP for a hearing test...

Hope you and Liam work this out...
