Having twins is often a challenge for parents, and Rebecca Romijn can certainly relate. The actress dished to PEOPLE about her twin girls, who have reached the dreaded "terrible twos."

"It's equal parts absolutely adorable and absolutely horrible!" she said about her twins, Charlie and Dolly, with husband Jerry O'Connell. She added that bedtime is no easy matter these days for the girls, who turned 2 in December.

"I'm just trying to get them to bed at night, but they're 2! That's what being 2 is all about," she said.

Even though Romijn and O'Connell walk red carpets with smiles, the truth is they feel just like every other parents of 2-year-olds: tired.

"There have been so many sleepless nights for my husband and I," she says. "If I can just get them to stay in their beds and shut up at night, I'd be happy."

And with sleepless nights comes sickness.

"Right now, I think the whole job of being a 2-year-old is just trying to get as sick as often as possible to build up your immune system," she joked.
