Mom-to-be Chrissy Teigen covers the April issue of Self and dishes on impending parenthood with husband John Legend.

On first-time mom nerves: “I’ve truly never been alone with a kid. I don’t think I’ve changed a diaper! I’m like, how many times a day do they go?… We are going to love the sh*t out of our kids, but we are going to team up and fight in pairs!”

On how she and John are different: “I’m a worrier, and he’s very laid-back. 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.”

On her hopes to have 4 children: “I think I’ll probably be pregnant all through my 30s. 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.”

On her struggles with fertility and enduring several rounds of in vitro fertilization: “The big question was why this wasn’t working for us when I was young and he was healthy. I thought, people get pregnant by accident all the time! How does this happen? Emotionally, it could be really hard. When you have these high-highs and low-lows, and you’re, like, cuckoo pants.”

On John’s support during their rounds of IVF: “He completely understands everything; he’s a sweet, sentimental, emotional guy. One of the things that saved us is that we never did that real fertility thing, where you’re looking at the ovulation clock and saying, ‘Honey, get home; we have to do it right now.’ John would say, ‘Let’s never be that couple that has to schedule sex, where we put it on the calendar and say, OK, this is our night.’ So before we did IVF, even if we went a few days or a week, our feeling was, it’s cool, who cares?”

On her go-to prenatal workout routine, Body by Simone: “I work out every day. I still feel fit and energetic. In a way, I’m healthier now that I’m pregnant. A lot of classes don’t feel like they’re tough enough on you, but some trainers have you rolling tires and stuff. And I’m like, ‘OK, I need something in between that!’”

On her new book Cravings: “I waited years to write a cookbook because I wanted people to know I really do love food. It always bothered me when someone would interview a model and say, ‘What do you do to stay in shape?’ and she would say, ‘I love to eat pizza; I love to indulge.’ I’ve always been the first one to say, ‘Bulls—! No you don’t.’ So I’ve been hyperaware of that.”
