Can I get a resting order on someone for my son before he's even here. I'm getting one myself.

No you cannot, not before he's born.

you can get a protection order before he's born

well my dad beat the crap out of my step mom and if my dog wasn't home he would of killed me. and he some how found out where I'm staying and I'm afraid he's going to try something. Cuz he said either way he will be in his grandsons life.

I'm to terrified to even leave my home

sorry to hear this.
