Family court advice please

Dear Mums
I am asking because I am desperate! 16 months ago we have been dragged through the family court process. Prior to going through family court my ds had never stayed with bio father and if he did spend time it was when I was there.
We unfortunately had a completely hopeless lawyer. The lawyer also setup with son’s bio father a completely shamed family report writer, without consulting me (who was completely chosen and paid for by the other party). As a result of this report and his fabricated affidavit the report recommended that my ds spend 50/50 shared time. As at the time I was an extremely high risk pregnancy, just prior to trail, I succumbed to 50/50 shared-care for my then 3 year old ds. I proceed to have a 3 month premature baby after the stress of mediation.
My ds hates his bio father and is completely distressed about leaving us. He is extremely confused why I send him there. Change overs are completely horrific when he is leaving us. I feel traumatised… I can only imagine how he feels. His bio father and I have a very negative relationship. However my beautiful husband steps in to fill in communication and avoids any extra stress for our ds.
Our situation needs to be reviewed by the family court. I am desperate to find an amazing family law lawyer in the Brisbane area! Any advice I would appreciate more than words.
