Recently separated from bd

So my bd and I tried to make it work for the sake of our son for the second time and it didn’t work out so now I’m stuck thinking about the holidays coming up and visitation. He’s not like your typical bd that cares to see his kid, when we were together he has every excuse in the book not to visit us even when he had days off of work, it’s been three days since we broke up and he has not yet asked about our son or to see him. My question is, what should I do when he asks to see him? he’s never taken care of our son alone because he said he was “scared”. He also doesn’t have a reliable form of transportation or a car that fits a car seat, he is jobless and lives with his aunt rent free. I’m not sure how he will visit our son since I personally don’t want to see him but don’t want him to be alone with him because he never cared to take care of our son when we were together, he refused to change poopy diapers and if my son had a rash he would refuse to put diaper cream on him because he didn’t like the way it felt on his fingers. I don’t believe he’s capable of hurting our child but he’s not a responsible adult, does anyone have any tips as far as what I should do for visitation and holidays??
