Pumping breeze

Love my new inserts! They make pumping so comfortable it doesn’t even seem like I’m pumping at times!

Ruby · Today

Beginner must have!

Ordered while still pregnant so I could be well equipped to start pumping once I was ready! Had no idea what my nipple size would be or how much it changes! I love these inserts!!
