Mayor Muriel Bowser announced that she would add 1,000 more spots this summer, but advocates say it’s still not enough.

Last month, worried that applying sunscreen would lead to inappropriate touching, Maryland health officials put in place a new policy at summer camps that steered counselors away from helping children apply sunscreen and forbid campers from assisting each other in the application of sunscreen. On Saturday, in response to dermatologists and parents who said the new policy would make it far more likely that children would suffer skin damage, the state health department scrapped the new restrictions.
