I'm 16..pregnant...and Need Advice Please

Hey everyone. I'm 16 years old and 8 months pregnant. Currently i'm living with my mom and dad. I only have one more onth until my son will be born and I don't know how to handle the living arrangments.
You see, as I said...I stay with my mom and dad. My dad stays downstairs while me and my mom stay upstairs. Me and my mom don't really speak to my dad and my mom works 7 p.M to 7 a.M 5 to 6 days a week. Depending on her schedule. My dad has had a hard time doing things ever since his stroke. It's real hard staying at home everyday all bymyself and it will be harder when the babys born because no one will be there. It makes it more difficult since i'm not close with my mother. She not really someone I could talk to. I wish I could, but sometimes she can seem so judgmental.
My boyfriend wants to be around and his mother said she wouldn't mind me staying over at his house so she could watch the baby until I get out of school. (i'll only be going for 4 hours) but I don't think my mom will approve of that. My mom lets me go over but she won't let me stay the night for whatever reason.... I would rather have my sons father to be around all the time or most of the time at least so he could take up responsibility for his son. We are real excited but all that worries us is : "what will happen after he's born?" could my mom still tell me what to do as much? I know i'm still a minor...But I have a baby now. And i'm trying to do what's best for me and my son. I do want to finish school and thats why my boyfriends mother is willing to let me stay at her house so she could watch the baby until I come home from school.
I also figured I could stay at his house when my mom is working, so I wouldn't be at home bymyself....And then when my mom is off I can go back home . Then a routine can form from there. Isn't that more reasonable?
My boyfriend and I are real excited about our baby coming and can't wait until he's in the world and in our arms. He wants to be a part of his life so much as well as mine. Especially since we have been together 4 years. I' just so frustrated with whats going on right now and what will go on later a month from now.

My main questions are: could my mom still tell me where I can stay and go with my baby? And tell me what to do? And she couldn't stop the father from seeing his son right? Especially after he signs the paper at the hospital saying he's the legal father?

I really need some advice please. Thank you so much. Much love!
