A bit of back-story, i'm expecting my first child due March 2019, i was with the father of my baby until i found out i was pregnant and he broke up with me when i told him, which was really hard for me to deal with. He already has a daughter, the mother of which is not letting him have contact at the moment due to some of his behaviour in the past and involvement with drugs. I want him to have contact with our baby, and would really appreciate his help as he's done this before and i do think he has changed but i still have some issues with trusting him.
When our baby is born i've told him that he can come and visit baby whenever, every day if he wants, to bond and help with care (we live in separate towns about half an hour apart and he works) but he expects joint custody pretty much from the beginning. I don't feel comfortable with passing a baby between us and two different houses at such a young age, babies need consistency. I also want to breastfeed for a while and he says i am using this as an excuse to stop him from having contact which is just not true.
I am happy to share custody but much later on, even now before baby is here i am very upset by the thought of having to be separated from him or her. Am i being unreasonable like he says? and what is a good age for my baby to start living between 2 houses? in my mind anything below 1 years old is too young and even then it will be hard for me :(
