Stick with loose-fitting, lightweight items made from a natural fiber such as cotton. If you're comfy in shorts and a T-shirt, Baby will be too. For outside, add a wide-brimmed hat to shield his face. Do this even on gray days.
Apply a broad-spectrum sunblock 30 minutes before going outside and again every two hours or if Baby gets wet. As a last resort, a little bit of block is okay for babies under 6 months. Look for zinc oxide or titanium dioxide and an SPF of at least 30.
If you're going to the beach or park, find a shady spot under a tree, umbrella, or canopy. Or consider buying an infant tent to bring with you. Sunglasses can protect Baby's eyes—choose a pair that blocks at least 99 percent of UV radiation.
A good rule of thumb: If you're thirstier than usual, Baby probably is too. Give him extra formula or nurse him more frequently on especially hot days. Kids older than 6 months can have water, but clear it with your doc first.
If Baby sweats a lot, he may develop heat rash—bumps that cluster on the neck, groin, back of the knees, or in the crease of the elbows. To relieve it, rinse the area with water, pat dry, and leave Baby undressed inside to help his skin cool.
