My son had a reaction to Coppertone Water babies a few years ago. He also has asthma and mutiple food allergies, and has no other reactions to soaps etc. I found that Banana Boat tear free kids 50+ lotion works great on him. When reading labels almost everything I have found has the same ingredients as the coppertone, including the banana boat sprays and the BB baby. BB kid lotion has the TD in it, and I am not sure what it is about the others that my son reacted to. I stocked up during a sale on the banana boat kids 50+ lotion after he didn't react to it, so I always have enough of it. I send it to school too, so they know only to use his sunscreen on water days or very hot days.
