What to do at hospital if not breastfeeding

How do I prevent my milk from coming in after birth? Did you ladies pump at first then pump less and less?

This is my second baby and I breastfed my son at first so I have no idea. Also, he was on similac for awhile and did horrible on it. I know every baby is different but can I bring my own formula and bottles instead of those ready made bottles they give you?
