curious soon to be mother of two

For mothers with more than one child. 
If you live out of state and have no family or even friends really how do you go about going to the hospital when it's time? 
Like I am so worried about my son can I take him with me is he even aloud to be in the room with me? How does that work we have no one except my husband and it's gonna be hard for both of us. Any suggestions or any moms had this experience?
