Anne Hathaway is handling motherhood like a pro and her husband, jewelry designer Adam Shulman, is quite impressed.

“She always amazes me,” Shulman, 35, tells PEOPLE. “As a mother, she is gorgeous.”

The happy couple welcomed their baby boy, Jonathan Rosebanks, on March 24.

Shulman, whose company James Banks, recently launched a collection inspired by characters and themes from the film Alice Through the Looking Glass, sang his wife’s praises during a Disney event launching the new line at Roseark in L.A. on Thursday.

In fact, Shulman says it was Hathaway, 33, who inspired his first collaboration with the company’s co-owner, Heidi Nahser Fink.

“My wife was away working and she said, ‘I feel like when I am away I don’t have the light in my life. I miss my family, I miss you, I miss the light in my life,’ ” Shulman explains.

It was then that Shulman got to work designing a necklace for Hathaway that now stands as the company’s trademark piece called The Light Keeper.

The designer says he is enjoying every part of fatherhood ­­­– even the dirty work.

“I love changing diapers! It’s the best,” says Shulman. “Every aspect of it is amazing.”

And he is equally smitten with his Oscar-winning wife. “Every day makes me appreciate her more,” he says.
