What kind of sunscreen do you use for children?

If it's 4th or 6th grade, it seems pretty big...

It's awkward to tell Pinkfong to use Greenfingers...

Which sunscreen do you mainly use?

I've seen a lot of ads saying that adult sunscreen sticks can also be used by children.

Is it okay to use it together as long as I focus on cleansing?

There are many physical sunscreens for kids, so they tend to leave a white cast, which I also find a bit bothersome.

Is there anything milder and without cloudiness, if possible?
