Raising two kids younger than the age of 2 isn't easy. But Heidi Klum has a secret weapon: husband Seal, who can change a mean diaper. "Sometimes he's better at that than I am," the supermodel – and mom to 2-month-old Henry and daughter Leni, 1 – says with a laugh. The German catwalker, 32, needs all the help she can get. Just weeks after giving birth, she walked the runway in the Victoria's Secret lingerie show (which airs on CBS on Dec. 6) and she's hosting the second season of her Emmy-nominated Bravo show Project Runway, premiering Dec. 7. Klum talked with PEOPLE about juggling career and family and sitting in the judging seat.
How are you balancing work and caring for two babies?
It is challenging, it's hard. I didn't really want to go back to work. I just want to stay at home. The weeks that I had off when I had Henry, that time just flew by. I never had off that much time – only when I had my daughter. But it's really about scheduling and having a great mom – my mom helps a lot – and a great husband. I have great help around me.
Seal clearly has a lot of patience.
I think that's why we're very attracted to each other. I'm very much the Speedy Gonzalez – I do a thousand things. When we go, I pack the bags in 10 minutes – I have this bottle, that bottle, diapers. I put the car seat in and the stroller's already in the back. He's still talking to Henry or putting a clip in Leni's hair. It takes longer for him, but I love that – he really takes his time.
Are you already seeing a difference between Henry and Leni's temperaments?
Boys eat so much more than girls do. His voice is very manly when he screams. His head was already up when he was born. Leni was two or three months when she could lift her head. The first day, people thought we were lying but we were like, "No, his head is already up."
What do you see of Seal in your son?
Right now it's really just the looks. Everyone who sees him says, "Oh my god, he looks just like Seal." And I'm like, "He has nothing of me? C'mon, there must be something of me in there somewhere." And they're like, "No, sorry, he looks just like his father." I'm a little sad about that (laughs).
