I agree. It's not hard to get an order to ban photos of kids being taken. Jeff Brazier did it when jade died and we haven't seen the kids since, not even pixilated.
I don't think any of the public should have a clue what a celebritys child looks like until they're old enough to decide for themselves whether they want to be seen in the media
Also those kids could then be spared some of the stories the media have done about them.. I.e. Suri Cruise.. The mail is obsessed with her.
Paul McCartney managed to keep his kids out the media and he is an internationally known star..so it's possible
