Chrissy Teigen is getting candid about becoming a first-time mom.

“I’ve truly never been alone with a kid,” the 30-year-old pregnant model revealed in a new interview with SELF. “I don’t think I’ve changed a diaper! I’m like, how many times a day do they go?”

Chrissy and her husband, singer John Legend, 37 — who tied the knot in 2013 — announced they are expecting their first child together last October.

Since then, the happy couple has talked hypothetical situations for their baby girl, who's expected to arrive next month. “I’m a worrier, and he’s very laid-back,” she said about the duo's opposite personalities. “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 Lip Sync Battle star additionally revealed she and John hope to have four children in the future. “I think I’ll probably be pregnant all through my 30s,” Chrissy said. “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.”
