I hope this helps as someone that has been through it with a newborn.
Firstly, I would recommend you get a mediator. Current family law matters manditory to attempt mediation prior to issuing proceedings. This may be free of charge in many service providers for concessioners.
I am sorry to say that mothers bodies and the best interests of children never seemed to come first in my experience. I lost my breast milk after I was threatened and intimidated by my daughters father and his dad (both very influential lawyers) that it would be "inflammatory" to bring my breast fed child to court at 12 weeks old. When I did, they both intimidated me and shook their heads at me and my 12 week old daughter outside of the Court - his dad and principal of his firm even gave me the rude finger from the bar table as he represented himself in a co flick of interest matter (as my former lawyers and the fathe of the respondent and grandfather of my daughter) that he consented to after it couldn't proceed to trial as it was meant to.
No one cared - they had a reckless disregard for our lives and the laws.
Get out of the system and away from lawyers that don't seem to care about women's bodies and children at all. You'll be lucky if they even bother to read your affidavit.
I do t want to scare you, I just want you to know the truth. The Courts don't care, they will force decisions on you, and in real life - they're not the parents you would want deciding a brand of water - let alone decisions over your children. Run- don't walk. Get a mediator and save a lot of financial and emotional hardship on you and your child.
You're a mother now, and you need to protect yourself from the cruel and inhumane treatment that the legal fraternity routinely commits against women and children.
