The day after your child is born, put in a claim to CMS. its very easy and you do it online.
About contact - you’d be mad to agree to one day a week right now. You have NO IDEA
how well or otherwise your birth will go
how well you will be
how well baby will be
how you will feed baby
how you will feel about being away from baby for more than an hour
how baby will cope with being away from you for more than an hour
So no, you can’t agree to anything right now. if you feel the need to reply, I’d say that you note all his comments, you are committed to doing what is in baby's best interest and that you will revert to him in due course.
Do NOT tell him when you are in labour. Do NOT tell him when baby is born until you are back home and feeling well enough for visitors.
BEFORE you contact your ex, go out and register baby with
your choice of first names
Your surname
Do all this without any discussion. You are still a person with human rights and you don’t need his permission to do any of this.
Then send him an email saying baby x born on this date Y weight and is well. That you will be back in touch to arrange contact with baby when you are recovered from the birth.
If he come to your house to see the baby, make sure you have a one of your friends or family member in the house with you.
Don’t phone him.
Don’t text him.
Send brief and polite emails so you have a paper trail showing that you are being reasonable. Don’t write anything that you’d mind being read out in court.
