Questions about pump parts and flange inserts

Answers come from each maker's published specs. Safety and health questions link to the agency or medical source.

How do I pick a flange size?

Breastfeeding and pumping: see the AAP's breastfeeding pages and the FDA's breast pump page. Check the label and the maker's instructions, and ask your pediatrician about your child.

How should I clean pump parts?

Breastfeeding and pumping: see the AAP's breastfeeding pages and the FDA's breast pump page. Check the label and the maker's instructions, and ask your pediatrician about your child.

What does "hospital grade" mean?

The FDA does not define "hospital grade." Look at the pump's own specs and whether it is meant for one user or many.
