"It can’t be said enough … you’re the heart and soul of every moment this family shares," Reynolds captioned a Sunday Instagram post of himself hugging his wife. "I’m grateful for the light and for the kindness you smuggle into each and every second of our lives. I see you in the eyes of our children … Every laugh. Every blink and every thoughtful moment of vulnerability. The tender grit it takes to be a mother in 2021 is an act of pure strength and heroism."
