Actress Thandie welcomed son Booker with director husband Ol Parker on 3 March.
In the snap, a blissfully happy Thandie can be seen cradling six-week-old Booker on her chest, while the tot rests on his mum wearing a striped all-in-one suit.
The Pursuit of Happyness star Thandie, simply captioned the photo: "Happy Holidays."
Thandie and Ol, who married in 1998, are already parents to daughter Ripley, 13, and nine-year-old son Nico.
Thandie, who has previously shared a photo of Booker's hand, announced the birth of her third child last month, tweeting: "Our baby boy is finally here! Booker Jombe Parker. Born joyously at home yesterday."
Ol also said at the time: "We had a baby, that's a beautiful thing. He's called Booker, and while he doesn't do much yet, I suspect him to be awesome."
