What is a good SPF for children in the sun?

Children should use sunscreens depending on their age. Between 0 and 6 months, you shouldn’t have the child outside, so sunscreen should not be used at all. Between 6 months and 1 year, they should use a physical based sunscreen, for example, something that has titanium dioxide or zinc dioxide. I wouldn’t use any chemical sunscreens until age 1 and after.
