Since welcoming son Crew in in late July, Jena Sims has been on the go plenty for both work and play. However, no matter where she is, the 2024 Swimsuit rookie prioritizes pumping for her baby boy, whom she shares with husband Brooks Koepka. And in order to help out fellow mamas, the 34-year-old revealed on her social media just how she does it while constantly traveling.

Sims shared both an Instagram reel and a TikTok video in which she filmed her process of pumping while on a trip to bring breast milk home to her baby boy. The Swim Search co-winner noted that she uses a portable breast pump by Spectra and breast milk storage bags by Nanobébe.

“Be sure to label each bag with the date and time,” Sims reminded her followers of packaging breast milk. “[And] most hotel rooms have a mini fridge, but legally if they don’t, they have to give you one because it’s for a medical use.”

After storing her pumped milk in the mini fridge, she shared how she cleans her pump parts in a hotel sink using a plant-based soap from Dapple, which she called “amazing.” Sims then put her pumped breast milk in a lunch box with a Ziploc bag of ice to store in her carry-on bag for the flight home.

She also recommended the Ceres Chill on occasions you need to keep your breast milk cold for up to 24 hours while on the go. “It’s like a YETI for breast milk, it’s the most brilliant invention ever,” Sims noted of the product.

“I’m not even with child but I’m saving this bc a sister learned some lessons today. 👏,” one fan commented.

“👏🏼👏🏼👏🏼👏🏼 You’re incredible!” someone else gushed. “Crew’s a lucky guy!”
