Can You Take a 4-Month-Old to the Beach?

Sun Protection

• Infants are especially vulnerable to sunburn and other harmful effects of sun exposure because of their sensitive skin. Though older children and adults can wear sunblock to protect against these effects, it is not advisable to put sunscreen on a baby who is younger than 6 months, according to pediatrician Hari Cheryl Sacks of the U.S. Food and Drug Administration. Because a baby's skin is thinner, this allows more chemicals to pass through into the bloodstream. Instead of putting sunscreen or sunblock on your baby, use a shade tent or umbrella to provide protection from the sun. Dress your baby in a protective sun hat and long but light layers of clothing to help block the sun without risking overheating.

Staying Cool

• Spending too much time in the sun can lead to heat exhaustion and heat stroke -- even if you are sitting in the shade. It's important to keep your baby and yourself cool. Spending time in the shade helps, as does limiting visits during the times that the sun is the strongest: usually from 10 a.m. to 2 p.m. When you are visiting the beach with a young baby, shorter trips are usually better. However, if you plan to be there for a long time, make sure you take plenty of breaks by heading inside for some cool air and refreshment.

Keeping Hydrated

• Dehydration is a big concern when anyone spends time in the sun. However, it is an even bigger issue for babies, as they are more sensitive to the loss of fluids but are also unable to tell you when they're thirsty or are feeling weak or tired. So it's important that you offer your baby breast milk or formula often. Watch for signs of dehydration as well, including fewer wet diapers, lethargy or fussy behavior. Get out of the sun right away if you notice any of these signs.

Other Considerations

• There are many other potential hazards at the beach besides the sun. The water can be overwhelming for babies, and salt water in the eyes can be painful. It's best to keep infants back from the ocean. If you must play in the water, stick to the shore where only an inch or so rolls up with each wave. Your baby can enjoy the rush of the water but won't be in any danger. Always hold her securely on your lap when you are in any amount of water. Sand can also be irritating to a sensitive baby's skin, and it can harbor a number of pests, including sand fleas and crabs. Keeping your baby dressed in long layers offers some protection, as does using a towel or beach blanket for her to lie on. Don't lay your baby directly in sand.
