That's my reaction to "'He's a laugh!': Victoria Beckham pokes fun at her son Brooklyn as she posts playful photo of him sleeping on social media" (in The Daily Mail).
The boy is 18 years old, by the way, not a baby or toddler.
What are the social media ethics between parents (or grandparents) and children? Isn't consent always required? Whose personal "branding" counts? I would think the person in the image has the greatest interest in image control and the photographer is wrong to interpose her own sense that the child is part of her brand.* Other people are not your handbags and chihuahuas.
A photo of someone sleeping flaunts the lack of participation by the subject. If you really were sensibly concerned with your own image — instead of egoistically presumptuous — you'd make it clear when your share sleeping-person photos that the subject of the photo has seen it and expressed happiness with the idea of your sharing it.
