I'm from brisbane and wonder if you have private health? I know not every one likes sleep schools etc but I work with paediatricians that are connected with the Brisbane Nurture centre (mother baby unit) at the north west private hospital. If you have private health u just need a referral from a gp or pead and it's fully covered by your private health? It's a week long stay and sometimes it's just nice to have a week to stay and get meals done, people to talk to (8 babies with their mums each week) and nurses to help and reassure you.

A friend has also been there with her little boy when he was a similar age and they helped her a lot with reading sleep cues and knowing how to help them settle to sleep ( with her in their with bub) so not cry it out specifically. There is a little bit of protesting but drf different to CIO methods.

Just something to maybe look into ?
