BBC3 presenter Cherry uploaded the cute snap last night (18 December) and it shows Edward sleeping with his arms in the air.
The cute baby is snuggled up in his favourite Boden London blanket and has a cosy hat on to keep his head warm.
Alongside the photograph, 32-year-old Cherry commented: "Doing a celebratory Mexican wave in a most excellent blanket #londonlove #christmassy."
Cherry, who is also mum to four-year-old daughter Coco, gave birth to Edward in October.
The documentary maker had Coco in front of the cameras for her TV show Cherry Has A Baby, but she decided to keep film crews out of the delivery suite this time around.
Speaking to Reveal before Edward's birth, Cherry said: "There wasn't a reason to do it this time though, as with Coco there was a documentary to make.
"I would never try to shoehorn it in. If something sprang up though, I wouldn't hesitate!"
