Prime Day's Baby Clothes Deal Includes 20% Off The Cutest Essentials

File this one under "summer necessity." This full-body swimsuit is "certified UPF 50+ so it blocks 98 percent of the sun's harmful UV rays." It's lightweight, dries quickly, and is chlorine and saltwater resistant so the bright, stripy design won't fade. These little suits make the beach so much more relaxing and fun, as they remove a lot of the stress and worry about scorching your little water baby's skin. They also kind of make babies look like little Liberaces, which I personally find to be a plus.

This three pack of long sleeve rompers runs from 0-12 months, and are a very cute and practical addition to your bebe's wardrobe. They're made of 100 percent organic cotton (making them super soft), and the sweet and simple design makes these great little play clothes that still have a bit of style. They're also made to keep a little one warm, which can be good now — when you're stuck in intense AC — or a few months down the road when fall kicks in.

These adorable footed jammies are another solid choice, and would also make a great gift. They're 100 percent cotton, and I love the whimsical designs of puffy clouds and a little rocket ship. There's also a jaunty pair that's patterned with bowler hats, mustaches, and bowties, for when you want your infant to evoke images of Rene Magritte or the 1920s.

I love everything about these super sweet sleeveless pajama sets, which are perfect for the sweltering dog days of summer. Put your little one in this cute little get-up, and maybe it will make the 3 a.m. wake-up call a teeny bit more bearable.

You get three sets of (100 percent cotton) short-sleeve bodysuits as well as three sets of pants with this deal. These are cheerful, easy ensembles for everyday wear and tear, and you won't mind when they get coated in the dirt, banana, drool, and general goo that babies like to accumulate on their wardrobe.

Every baby needs a sunhat, and this reversible number has a wide brim for extra SPF protection, as well as a handy chin strap to thwart ye olde hat-yank-and-throw that little ones are so fond of. It also comes in some bright and playful patterns, with drawings of polar bears, fish, and lemons.

I realize some parents might not classify a watermelon-patterned tasseled romper with matching headband as essential, but I personally kind of do. I mean look at that cuteness. And it's only $9.59 with Prime. That's less than a pack of diapers. This snazzy, breezy little number is great for picnics and parties, or for staging your own photoshoot with baby trying her first slice of actual, real watermelon. Which I imagine will go poorly, but will yield lasting summertime memories.
