Neutrogena is a well-known and trusted brand moms can rely on. This hypoallergenic Neutrogena Wet Skin Kids ($8) sunscreen stick has an SPF of 70 UVA and UVB protection and is water resistant for 80 minutes. What's great about this stick is that it can be applied to both dry and wet skin, so your child doesn't have to dry off before reapplying. Score!
