Access to baby with shift work

[kuvvy0606]

Me and my ex have a 9 month old. He works sporadic shift work, often nights and has 2 split rest days a week (sometimes together). We have never lived together, but he has just come to visit when he had time. I breastfeed and have never left her with him apart from a few hours. This is due to the fact that he has mental health issues, has attempted to overdose and commit suicide and when I was pregnant threatened to crash the car with me in it.
I am wanting to know what is reasonable access at this time, he is saying he wants 50:50 and I have said no in mediation and he will now be taking me to court.

I'm curious as to what you ladies think is a reasonable amount of contact, I was thinking 1 full day and also an afternoon per week?
Do you think that is ok?

Just to add as well, he sends me his shifts on the Thursday for the next week. He only gets them 1 week ahead, which is a pain but I want to be flexible!

My partner reduced his days at work to be able to facilitate contact with his baby. When his work got arsey, he got a new job and quit. His child was his priority, so he fit the rest of his life in around that.

He had 3 days a week building from 30 mins to full days and overnights over a 6 month period. She wasn't breastfed though.
