The star recently spoke with PEOPLE and shared some of her tricks for getting her two sons to wear sunscreen.

"I feel very lucky that my boys are not super squirmy," the expectant mom told PEOPLE. "They recognize [that] I've always been that mom that's like, look, I am going to pick your boogers and I'm going to slather you with moisturizer out of the bath. That's just all they've ever known from me."

"So putting another product on top of that when we're out in the sun doesn't really bother them or affect them. They're like, 'Oh, this is pretty routine for us,' " Moore shared.

While her boys are mostly good about tolerating sunscreen, Moore said she still has to act fast.

"It's as quickly as you can get something on. My guys are not going to sit still by any means, but they also recognize, 'I've just got to kind of grin and bear it because this is who my mom is,' " she teased.

In May, Moore announced that she is expecting her third baby with husband Taylor Goldsmith, sharing the news on her Instagram.
