The 44-year-old Mom star gave birth to the boy, her and the Jurassic World actor’s first child, in August 2012, nine weeks before her due date.
“Please join me in supporting GAPPS (the Global Alliance to Prevent Prematurity and Stillbirth) on Thursday, May 6th at 6:30pm (PDT),” Anna wrote on Instagram on Wednesday, April 28, alongside a black and white photo of herself smiling at baby Jack, who stares at her while wearing a feeding tube. “I will be sharing the story of my son’s preterm birth 8 years ago as part of @healthybirths 60 minute virtual fundraiser.”
Another photo of Anna with baby Jack was posted on GAPPS’ Instagram page.
She and Chris, 41, have spoken about their son’s birth before. The infant weighed just 3 pounds and 12 ounces when he was born. He spent a month in the NICU before Anna and Chris brought him home.
