When I was in the hospital they gave me a new set of tubing and other pump parts, but I had to pump right away since the baby went to the NICU. When I had the second baby I didn't worry about the pump parts being new for each child as long as I got them new in the first place. I just washed them well and used the microwave sterilizer bag to sterilize them (you can get the bags at most baby stores).
