Summer Wardrobe Prep for Kids: The Only Checklist You'll Need

The biggest summer-clothing mistake is buying for how it looks on the hanger instead of how it performs at 92 degrees. Polyester blends — even cute ones — trap heat and sweat against the skin, which is how you end up with a cranky kid and a heat rash by lunch.

Stick to 100% cotton, linen, or cotton-blend muslin for anything they'll wear in direct sun. These fabrics breathe, wick moisture, and dry fast when they inevitably end up in a sprinkler. Linen wrinkles like crazy but it's the coolest fabric on the planet for hot weather, so make peace with the crinkle.

Color matters too. Light colors reflect heat, dark colors absorb it — that's why your kid in a navy shirt is melting at the park while the kid in white isn't. For long days outside, lean light. For stained-magnet ages (basically two through six), forget white altogether and go for prints that hide popsicle drips.

And the sizing trick that saves the most money: buy bottoms true-to-size and tops one size up. Kids' waists don't change much in three months but their torsos shoot up fast, and an oversized tee just looks intentional.

A wide-brim hat does more than a baseball cap. The brim has to wrap around the back to cover the neck and ears — that's where pediatric dermatologists see the most sun damage on little kids, because parents remember to put sunscreen on the face but miss the back of the neck under the hairline.

Sunglasses are worth fighting for, even if it's a battle. UV exposure to the eyes in childhood is linked to higher rates of cataracts and macular issues later in life, and kids' lenses are clearer than adults' — meaning more UV gets through. Look for "100% UV protection" or "UV400" on the label. The price doesn't matter; the label does. A $6 pair with UV400 protects better than a $40 pair without it.

For babies under six months, sunscreen isn't recommended — their skin absorbs chemicals too readily. That makes hats, lightweight long sleeves, and shade the entire strategy. A stroller canopy plus a muslin swaddle draped over the sunny side works better than people think.
