In the snapshot, Thiessen’s 5-year-old daughter Harper held her baby brother in her arms as they both took a nap. Holt — already showing off his dark locks — wore a gray onesie and was wrapped in a matching blanket.

Thiessen’s husband, actor Brady Smith, also shared a photo of his son from the hospital. “Feeling incredibly grateful & blessed at the moment,” he wrote. “#sweetbabyboy.”

The Beverly Hills, 90210 alum and Smith, 43, welcomed their second child together on Wednesday, July 1. Thiessen was the guest of honor at an L.A. baby shower in April.
