Wonder Years alum Danica McKellar will welcome her first child with hubby Mike Verta in September!

"It feels really great," the actress, 35, told at the Inception premiere in Hollywood on Tuesday. "I feel blessed to be having a really easy pregnancy."

Part of the ease comes from altering her diet, which now includes hormone-free food.

"I've been just eating very healthy, all organic, no sugar, white flour, nothing artificial," she told Us. "I'm being so incredibly strict...not a lot of meat!"

And though the actress knows the sex of the baby, she plans on keeping it a secret -- for now, at least.

"We're not saying anything till September" she said coyly.

So has her former Wonder Years co-star Fred Savage offered her any friendly parenting advice?

"Well, he's got two kids and he hasn't offered me too many tips yet, but he's just told me, 'I always knew you'd make a fantastic mother,'" she told Us. "I just saw him a few weeks ago so that was a lot of fun."
