Behati Prinsloo and her baby boy are ready for summer! The model shares three kids with husband Adam Levine — daughters Dusty Rose, 7 and Gio Grace, 5, and a baby boy whose name they haven’t shared — and it seems like Prinsloo already has one of the most important warm-weather essentials on standby.

She posted the sweetest picture on her Instagram Story of her little boy squatting in what looked to be the shallow end of a pool. The photo is from behind and you can see just how long his brown locks have gotten! He seems to be sporting a colorful necklace or two, and he’s wearing nothing but a swim diaper. Because with the brand he’s wearing, it’s really all he needs.

“@coterie Swim diapers👌🏼,” Prinsloo wrote over the photo.

If you’re unfamiliar with Coterie, let me introduce you to the award-winning company that has been dubbed the “Rolls-Royce of Diapers.” Their hypoallergenic, dye-free, fragrance-free diapers boast 70 percent more liquid capacity and 12-hour leak protection, making them especially good as an overnight diaper.

After raking in the awards and rave reviews, the company branched out into “The Pant” (more of a pull-up style) department and made a swim diaper that they’ve dubbed “The Swimsuit.”

They’re (of course) even more absorbent than the standard Coterie diaper, and have all the safeguards to ensure that nothing gets outta there. But our favorite detail is probably the plant-based core that is made with a “no-swell” design that won’t balloon or sag in the water.

…Cuz who wants that? A saggy diaper is not the look we’re going for when it comes to poolside photo ops.

The Coterie swim diaper is so popular that they’ve already sold out in all sizes. And summer has just begun! But don’t worry, there’s a waitlist you can join for these next-level diapers that have super cute patterns. “You all really love The Swimsuit! It’s currently sold out due to high demand, but we’re working as quickly as possible to restock,” Coterie said.

“These are by far the best swim diapers we’ve used for my son,” one happy customer said just last week, and that’s all we needed to hear.
