Pumping Question

I was exclusively pumping for my daughter until December 2019. I plan on pumping with this baby as well, but have some questions. Does anyone who has breastfed multiple times know if it is ok to reuse bottles and the such that you use to pump into? For instance I have the freemie cups and would love to use them again. I assume with proper sanitation they should be safe, but wanted to check!

I plan on talking to my OBGYN about it, but thought I’d ask here as well!
