Pumping?

My c-section is next Wednesday should I bring my mom cozy’s s12pros? Because my doctor wouldn’t give me a prescription for a breast pump. He wouldn’t give me a prescription because he said the hospital sends you home with a much better one then you get though the insurance. Which when I had my now 16 month old son they only sent me home with a manual hand pump. So I only have my Momcozy. I plan on just pumping only. Can I give baby formula and pump every time I feed my baby? When my milk comes in I will just give my baby my breastmilk. Reasons why i don’t want to breastfeed is because i don’t think i really understand how to latch my son on the lactation consultant in the hospital didn't show me well. So i don't want to put my baby to the breast.
