In the adorable snap, the youngster was playing with some magnetic blocks, and he looked to be having a great time.
To make sure that his face was covered, the young boy was wearing a captain's hat as he stood at the table.
"@robbiewilliams Captain Charlie #weekendvibes #family #boysandtheirtoys AWxx," the loving mum wrote.
Fans fell in love with the sweet picture, as one enthused: "I can't get over how grown up they're all getting!!"

"Thank you for sharing this…have a wonderful weekend/father's day with your biggest boy and family!"
Ayda frequently fills her Instagram feed with cute snaps and clips of her brood, although she always makes sure to obscure their faces.
Earlier this month, fans' hearts melted when the former X Factor judge shared a sweet reaction her daughter Coco had when she was serenaded.
The little girl could be seen from the back, wearing a white long-sleeved top and with her blonde hair pulled back into a ponytail.
The parents always hide their children's faces
Coco ate cereal as she danced in her chair to the guitar music that her grandma's boyfriend was playing as he stood in the background.
Ayda captioned the sweet behind-the-scenes moment: "Coco getting serenaded by mum’s boyfriend, Ian, at breakfast #cocopow #musiclover #breakfastwiththewilliamses AWxx."
Her followers were quick to share their appreciation for the clip, with one writing: "She’s very musical like her daddy!! Beautiful to see!!"
Others commented: "This is just lovely," "TINY DANCER," and: "Adorable!!!!"
