Single mum

So I’m 22, I’m 7 months pregnant. The babies dad is 30, wants to be included with baby but we aren’t together. Any of you single mums can give advice on when baby is born, how will we ‘share’ time equally with baby. I’m a bit scared of giving birth then letting go of baby to him, he’s got 2 kids so will be a good dad but still nervous and not sure how we go about this. We’ve discussed moving in together for first 3/6 months, but he’s got a 1 bed house and has his 2 kids over regularly....
