“Not my best thought out adventure. Three dogs, a toddler, and #30weekspregnant #gladwemadeitback,” Smart wrote on Instagram on Wednesday, giving an update on her pregnancy as the caption for a photo of her 2-year-old daughter Chloe and the family’s dogs playing in the snow.

The couple first announced their pregnancy on Halloween, when Smart shared an adorable photo of her family dressed as skeletons, saying they were “adding another skeleton to our little clan.” She broke the news that she’s expecting a boy a month later by sharing a photo of her ultrasound.

Smart, who was kidnapped from her family’s home in 2002 and rescued nine months later, has been open about wanting to be a mom.

“That is my greatest aspiration — to be a mother,” She told PEOPLE in 2014. “We’ll start having kids and see how I handle that and then go from there. I don’t have a predetermined number in my head.”
