There is also a special type of clothing that stops UV radiation. This type of clothing offers protection similar to a sunscreen with SPF 50. You can buy this type of outfit from Beach and Bandits. Make sure to also wear a hat with a wide brim to protect your face.
But beware: you must also apply sunscreen on all body parts that are not covered. Use a sunscreen with a mineral filter, like our Naif Sunscreen, to maximize the sun protection. Re-apply sunscreen on yourself and your child every two hours. You can read more about sun protection here.
