Chrissy Teigen is in full-on nesting mode!

The 30-year-old model is nearly ready to give birth to her first child, a girl, with husband John Legend, but recently admitted, "I've truly never been alone with a kid."

In her SELF magazine cover story, Teigen said: "I don't think I've changed a diaper! I'm like, how many times a day do they go?" But her 37-year-old husband may be a tad more experienced. "[John] has a big family with nieces and nephews, and he actually knows more than I do about kids," Teigen told the mag. "It's going to be very sexy to see this new side of him."

Teigen hinted that a few parental disagreements would be inevitable down the line. "I'm a worrier, and he's very laid back," she said. "I like to ask him little questions, like, ‘What would you do if our kid is 16 or 17, and we’re at dinner celebrating and having wine. Would you let her have some wine?’ And he’s like, ‘Yeah.’ And I’m like, ‘I don’t know if I would!’ I am the crazier one in the relationship, and he’s more relaxed, for sure."

The couple, who wed in 2013, have been open in recent months about their struggle to conceive and experience with in vitro fertilization. Teigen also recently revealed that she and Legend had specifically chosen to have a daughter. "I've made this decision," she told People. "Not only am I having a girl, but I picked the girl from her little embryo. I picked her and was like, 'Let's put in the girl.'"

Now, Teigen is already thinking about expanding her brood.

"I think I'll probably be pregnant all through my 30s," she told SELF. "I’ve always pictured everyone around the table for the holidays and together once a week. It’ll be heartbreaking if it doesn’t end up happening, but hopefully it will. We’ve got some embryos on hold."

And, yes, she does have an exact number in mind.

"Four is good, I think. And then, maybe a dog after," she said. "I hope that when we do have those four kids, John and I can look at each other and know that it's us against them. ... We are going to love the s**t out of our kids, but we are going to team up and fight in pairs!"

For his part, Legend has spoken with ET multiple times about his take on the pair's child-rearing philosophy.

"I think you just want to raise your boys and your girls to be smart and confident and self-aware and, just be good people," Legend told ET earlier this year.

At A&E's Shining a Light concert event in November, Legend got candid about how he'll teach his child about racial equality.

"Part of it is just by example," he said. "Showing that you love your neighbor, and not just your neighbor next door, but your neighbor across town, and across the world.”

"Teaching them what it means to love one another," he continued. "I think if you start your kids with that, love, and kindness, and being inquisitive, and caring about visiting other places, I think all that helps develop empathy. Hopefully if all kids have empathy, then we're in good shape."
