Heidi Klum has being a mom of four down pat, but playing her kids’s tooth fairy may have fooled her.

“Teeth are falling out, [but] the [kids] don’t mind it because they get money. I messed it up with the very first tooth that came out — I gave 20 dollars,” Klum, 40, told PEOPLE Tuesday at a Operation Shower event for military moms, sponsored by Babies ‘R’ Us.

“I had no idea. I thought 20 bucks was the right thing to do with the first tooth, but now with four kids and all of these teeth that are coming, it’s another small fortune.”

The Project Runway host says when it comes to balancing her career and kids — Lou, 4, Johan, 7, Henry, 8½, and Leni, 9½ — she’s like every other working mom.

“I have to schedule and plan my life really well [so] that I have enough off days with my family,” she explains. “The weekends, for example, I don’t work and I’m always home at the end of the day to have dinner and bath and bedtime. I get out of the house early so I can come home early.”

She adds, “Sometimes it’s the other way around, where I have night shoots and then I’m there with the kids in the morning.”

As for what has surprised Klum the most about being a mom?

“How much you can love and that you can love them all equally the same,” she says. “Because you do get worried, ‘Am I going to love one more than the other?’ But you don’t. They’re just all amazing.”

Not only is Klum a mom and TV host, but she has also designed a kids collection, Truly Scrumptious. “Everyone is getting a crib. Everyone is getting a stroller. Everyone’s getting a diaper bag and everyone is getting my collection,” shares Klum, who gifted her goodies to all of the moms that attended the baby shower.

“I think that they really deserve to have a fun day today. I wanted to be a part of that and gift them a lot of fun things.”
