Hilary Duff Says ‘4 Kids Is a Truly Wild Choice’ as She Shows Off Her Baby Bump

The Disney Channel alum announced in December that she was expecting her fourth baby — her third with husband Matthew Koma

Hilary Duff is reflecting on the prospect of being a mom of four.

In an Instagram post on Sunday, April 7, the pregnant Disney Channel alum, 36, shared a series of photos of herself posing with her husband, Matthew Koma. She showed off her baby bump and shared her thoughts about soon welcoming a fourth child to their family.

"4 kids is a truly wild choice," Duff wrote in the lengthy caption, before praising Koma, 36, for his support. "And while you rage the farmers market with the kids after 4 nights of shows and late nights so I can get some sleep and not hear mom mom mama mommy mooooom just know this only works because of you ♥️."

"Also on a separate note…." she ended the post, joking: "Why can I sleep during the day this late in pregnancy and not at night 😣😵‍💫."

In the series of photos, Duff could be seen lying on Koma's lap, as she wore a pink sweater and a long white patterned skirt. Koma sported a pair of jeans and a red button-down shirt, and the couple's dog lounged next to them on the couch.

Duff is already mom to three kids — she shares daughters Banks, 5, and Mae, 3, with Koma, and son Luca, 12, with her ex-husband Mike Comrie. This baby will be the last for Duff and Koma, after he revealed he had a vasectomy in March.

At the time, the musician shared several snaps and clips documenting the experience on his Instagram Stories, starting with a selfie in a car with the caption, "It's vasectomy day!!!!!!" before adding another of his "vasectomy fit check" as he snapped a mirror selfie of his outfit.

Koma then shared more mirror selfies while waiting for the procedure in the hospital, revealing he had taken a Valium and was "feeling hyped." In another selfie in his hospital cap and gown following the procedure, he wrote, "It's honestly not bad at all. Like better than going to the set dentist for sure."

Duff and Koma tied the knot a few days before Christmas in 2019. A source revealed to PEOPLE at the time that the ceremony "was small and low-key" with "only family and close friends" present. It was officiated by Duff's Younger costar Molly Bernard, as well as actor Christopher Mintz-Plasse, and took place in the front yard of the couple's Los Angeles home.
