It would be very risky to attempt a visit with your situation. There is a high likelihood that you would be held for the county that has a warrant out for you.

We would strongly advise you to not go to any visitation. They run your identification against the outstanding ​warrant list and will detain you if you are wanted.

We would strongly advise that you call the facility visiting room and get the rules. If they are doing an NCIC background check, it will come up. Most times if you get permission after letting them know you want to visit, they will grant you approval.

You might have a problem if the warrants come up when your name is searched in the NCIC database. 

Unless there are some restrictions on this particular inmate, they should be able to get a visit after the first week

They are brought in through the visiting room by visitors. I've seen inmates get fresh sneakers from the visitors, where they change shoes during the visit. The same thing goes for other articles of clothing where they are worn into the visiting room and then swapped with the inmate.

Possibly. You will have to petition the warden (or captain) for a special waiver. Being that you are a parent would elevate your chances higher than if you were not.
