“Happy Monday,” the Just Like Fire hitmaker, 37, captioned the image of her newborn donning a onesie that read, “Straight Outta Mumma.”
In January, the proud mama posted a photo of her son rocking an Adele-inspired onesie.
Also last month, the Raise Your Glass hitmaker and her family-of-four attended the Women’s March in Los Angeles.
Joined by husband Carey Hart and their two children – including 5-year-old daughter Willow – the Just Like Fire singer shared shots from their march.
“We march together,” she captioned the image holding up a “Unity Love Equality and a Dash of Nasty” sign while babywearing her son.
Hart, 41, was photographed standing in front of Willow who held up a sign of her own, reading, “I’m Strong I Love.”
“Today we march,” the mom-of-two captioned an image of her sign.
The Try singer and her former motocross freestyle racer husband welcomed their second child on Dec. 26.
