is famous for her multitasking career as a singer, actress, designer and dancer. But motherhood has taken her juggling act to a whole new level.
Until recently, Lopez and husband Marc Anthony, who welcomed twins Max and Emme in February
, didn't have a nanny to help out with child care.
"I did it for a long time but we started using a nanny a few weeks ago," says Lopez, 39. "[Most days] I get up early with them. Then when the nanny comes, I can take a shower and give them their breakfast. She's there to help me get things done."
As for getting back to work, Lopez says she'll take it a day at a time. "It's gonna be a learning experience. How will I do both? I try to take breaks from work," she tells PEOPLE. "I'll do a little work with the choreographers and then come back. I try to spend every free moment with the babies."
The mornings are her favorite time with the twins. "When they see you and have that big smile on their face – I live for that," she says. "And when I put them to bed at night and they melt in your arms. I give them a bottle and wind it down. I say, 'It's time for beddy-bye.' I hold them and sing a little song. By the time you know it, they are asleep."
Adding to her bliss: Lopez is perfectly happy with her post-baby body. "The triathlon really helped get me in better shape, and snapped me back into my body," she says, referring to last weekend's Nautica Malibu Triathlon
. "I don't weigh myself a lot. I still have 10 lbs., or so. [But] I don't have any problems with it. I never felt I had to get rid of it."
Asked how she stays so sane about her body image, she laughs: "We like to eat!" On a serious note, she adds, "I think you have to love yourself and indulge when you want to, as well as be happy and just have a healthy attitude towards it."
Besides, she notes, "Marc loves the way I look!" RELATED GALLERIES:
