CHRISTINA AGUILERA & MAX
Age: 15 months

"Being a mom has made me do things I never did before. I'm a total vampire—but Max makes me go out into the sun or to the pool in the middle of the day. He brings out a different side of me that I'm really starting to enjoy. Also, I never knew how beautiful the sound of laughter could be until my son started laughing. Tickle time is a very happy time! He loves when we're silly, and he has a very silly mom, so it works out great."

ANGIE HARMON & EMERY
Age: 4 months

"I've always been a pretty skinny girl, and now I've got boobs and a rear end! It's kind of fun, so I'm trying to figure out how to get back in shape but still keep these new attributes. I always say it takes a full year to get back to where your body was before you gave birth—and I can't even crack open a book, much less get to the gym! I have that moment when I get in the closet and nothing fits and I'm frustrated. I'll tell my husband, 'Nothing fits!' And he'll say, 'Yes, but you have a healthy baby.' It's so true."

MILLA JOVOVICH & EVER
Age: 18 months

"By the time I had my baby I weighed 197 lbs.—I gained 75 lbs.! For the first time I understood what it felt like to be a heavier person. I would go into a store and the salesclerks would give me an attitude, or sneer because I was asking for a size they didn't carry. I never expected people to be so judgmental of a pregnant woman! It changed my views of being beautiful, because in my eyes I was beautiful."

NATALIE MORALES & LUKE
Age: 8 months

"I am not walking the schoolyard thinking I am a hot mom! There was a time in my 20s when it was about looking cute in a little black dress. Now it's about what I am able to give my children: the confidence and the right healthy attitude for life. That's what beauty is to me."
