What to bring to the beach for a day with kids

For a day at the beach with children, pack for four needs: sun protection, water and food that stays safe, a complete set of dry clothes, and a few play items that work in sand. Many short beach trips end early for a simple reason. A child gets sunburned, overheated, cold after swimming or hungry, and the adults have nothing on hand to fix it. A bag that covers those four needs usually makes the difference between a long afternoon and an early drive home.

Sun protection for every age

Sunscreen is the item that is easiest to forget and hardest to fix once the day is underway. Use a broad-spectrum sunscreen with an SPF of 30 or higher, and apply it about 15 minutes before going outside so it has time to settle onto the skin. Reapply about every two hours, and again after swimming or towel drying, even when the label says water resistant. Cover the places children tend to miss, including the ears, the back of the neck, the tops of the feet and the scalp along the parting. A wide-brimmed hat, a long-sleeved rash guard and sunglasses with UV protection reduce how much sunscreen is needed in the first place.

Babies need a different approach. Pediatric guidance generally says to keep infants younger than six months out of direct sun and to rely on shade and covered clothing, using sunscreen only on small areas of skin when shade is not available. Ask the child's doctor before using any product on a very young baby. Older babies and toddlers can use a child-appropriate sunscreen, but they should spend the hottest part of the day under an umbrella or in a tent rather than on open sand.

Water, snacks and a cooler that stays cold

Pack more water than seems necessary. One common approach is at least one full bottle per person, plus spares kept in the shade, with sips offered at regular intervals rather than only when a child asks. Children absorbed in digging and wading often do not notice how much they are sweating, and a breeze can hide it further by drying the skin quickly. Dry snacks such as crackers, whole fruit and sealed bags of cut vegetables hold up well in warm weather. Yogurt, cheese, cut melon and sandwiches with meat or egg belong in a cooler with ice packs.

The USDA's general guidance is that perishable food should not sit out for more than two hours, or for one hour when the air temperature is above 90 degrees Fahrenheit (32 degrees Celsius). Food that has passed that limit should be thrown away, even if it looks fine. Keep the cooler in the shade, open it as little as possible, and store drinks in a second cooler so the food is not uncovered every time someone wants a sip.

A dry change of clothes for every child

Pack a complete change for every child, usually in a zip bag or dry bag. A full set includes:

• Underwear and socks
• A T-shirt and shorts, a skirt or a dress
• A light layer, such as a hooded sweatshirt

Keep wet swimwear and damp towels in a separate bag so they do not soak the dry clothes on the drive home. The light layer matters more than it seems. Children who have been in the water for an hour often get cold once the wind picks up or the sun drops behind a dune, and a warm top is quicker to put on than a search through the car.

Footwear matters as well. Sand that has been in full sun since morning can be hot enough to hurt bare feet by midday, and rocky shores have sharp edges and slippery weed. Water shoes or sandals with a strap that stays on in the sea let a child walk down to the water and back without a fuss. If children tend to lose one shoe in the surf, pack a spare pair.

Play gear and water safety

Bring a few items that are easy to carry and hard to lose. A wide bucket with a handle, a shovel with a flat blade and a fine-mesh net for shallow water cover most sand and rock play. A light ball tends to blow away in wind, so a small soft ball or a paddle ball that stays close is often easier to manage. Leave glass containers and valuable toys at home, since sand gets into everything and glass is restricted on many beaches.

Water safety deserves a place in the bag as well. Children who are not strong swimmers should wear a U.S. Coast Guard-approved life jacket that fits the child's weight, and the fit should be checked before they go in. Young children and weak swimmers should stay within arm's reach of an adult. Swim near a lifeguard, in the area marked for swimming, and check the warning flags before going in. Assign one adult as the water watcher whose only job is keeping eyes on the children in the water. Splitting that role among several adults who are each reading or talking often leaves nobody watching. A basic first aid kit with bandages, tweezers and antiseptic wipes completes the list. For anything more serious than a scrape or a bee sting, the lifeguard or the local emergency number is the right first call.

The easiest way to make this list work is to pack the night before and keep the beach bag by the door, with the sunscreen and hats in the top pocket where they are the first things reached for. Keep a small backup change of clothes and a towel in the car, since the day that goes wrong is often the one where the planned bag stayed at home. Once the bag is ready, the rest of the day usually settles into a steady rhythm of water, shade and snacks, with plenty of time for children to dig, wade and explore.
