hi there,
My son is allergic to almost every type of "hypoallergenic" sunblocks. he breaks out in a rash all over his body. the only thing i have found that works well is a cheaper sunblock called baby blanket- titanium dioxide formula. it's for sensitive skin and waterproof and it really works well. you can find it at all the drug stores for less than 10 dollars. big pink tube- you can't miss it. My sister just started using it on her kids too. hope this helps! -M.
