Hilary Duff's Mother's Day: Time With Luca And Helping Moms

It's a big weekend for Hilary Duff -- she's celebrating her first Mother's Day!

Duff and her husband, Mike Comrie, welcomed their first son, Luca Cruz, on March 20, and in addition to tackling motherhood for the first time, the star is giving back to those in need just in time for the special holiday. She recently partnered with the Johnson's Baby Cares program which, along with Save the Children, will provide necessities to new moms and babies in the wake of crisis situations.

"Being pregnant, and being a new mom, I've really been touched and inspired by initiatives to help other moms and babies," Duff told The Huffington Post.

Duff will work with the program to help assemble baby care kits, which are filled with basic infant hygiene products that both moms and babies desperately need, especially after a natural disaster.

"I can't imagine being put in that position," she said. "It's hard to be a new mom, and it's hard to take care of a baby, and when you add [a natural disaster] on top of it, it's just really challenging."

So far, the program is definitely paying off. Since its April launch, Johnson's Baby Cares has raised $100,000 for Save the Children -- just in time for Mother's Day.

As for Duff, while she's not sure what her plans are for her first Mother's Day as a mom, she has a feeling Comrie will pull through.

"I don't know what's in store for me," she said. "I think he has something up his sleeve, but I'm not sure. He's very good with surprising me with stuff, but we have a seven-week-old, so I'm not sure how extreme it will be."

She added that though she's excited for her first Mother's Day with Luca, she's also looking forward to spending time with her own mom.

"It's wild being a mom now, and how you feel toward your mom afterward. It definitely changes," Duff said. "So much just clicks. You're like, 'Oh I get it! I get why you told me "no" all those times. I get why you're so protective over me.' And it continues now, when I'm 24 and married. She still treats me like that. I just appreciate it now, because I feel like I'm going to be doing that to Luca -- I just feel so protective over him. And you appreciate the hard work they put it in, because it's definitely hard work, and the patience and the love. The list goes on and on."
