I can't bring to mind any celebrity's child, what they look like etc, at this age.
There's a few. Blue Ivy Carter is the most obvious example: her parents are very much working on making her a star. Will Smith's kids. Brooklyn Beckham. Kate Moss's daughter. Gwyneth Paltrow's daughter.
I don't agree with it myself: I respect celebs who keep their kids private. I also disagree with A-List parents buying their children careers when said children lack discernible talent (this may or may not include the names I listed above - take your pick).
Not just because I despise nepotism, but also because I strongly believe that children should be free to make their own choices about their future career paths. That can be quite difficult to do when you're being dragged out on the red carpet as a teen, and a career in showbiz presented to you as the only way.
H&M's kids are in the line of succession, so I'd say there is a decent argument that they should have some limited public profile. It's all part of H&M's rather precarious category status: sort of royal, sort of celeb, not fulfilling either role terribly well, because they don't mix.
But as for regular celebs, I like the ones who keep their kids private.
