There is one suncream called moi moi (i think thats what it is) it is for babies and has no perfume or bad chemicals in it. It is quite expensive but it is great, i think most chemists have it and i think it was around $20.

My 4yo dd3 is allergic to sunscreens and this one is fantastic and smells like baby powder so i can't stop smelling her when she has it on.
