Baby bumps : brought smile to my face as you are ofcourse right. Some love it, some hate it; but this is pretty mixed across all cultures.
The photo issue is a lot more divisive because of the fact, just a generation ago, everyone took photos with no worries.
Since then, mostly in the past 10 years, NorthAmerica and UK (and very little bit Europe) have gotten caught up with hysteria while the rest of the world has carried on with photography as nothing has changed.
They hysteria I'm referring to is the "someone took a picture of a child, must be a peado or going to spread it to bunch of paedos on the internet". Forget strangers, parents and grandparents are no longer able to take pictures of their brood without getting banned and hassled. Cant take pictures at the mall, cant take pictures at swim meets, cant take pictures at school plays, cant take pictures at the playground. *arrgghh*
(There are also offshots of this that have been voiced in this thread. "Dont touch my baby, you must be a paedo", "Dont go near my baby, you have germs" and other similar fears.)
Such fears dont exist in many parts of the world and they dont exist in China. Combine that with the curiosity Chinese have with little ones that look different, and we have the clash of cultures.
BTW: I was in Shenzhen airport yesterday on my way to northern China. Out of nowhere, 3 guys showed up with big grins and 1 camera between them. First they started snapping pictures of me and after a few (not before) they asked to pose with me, one at a time, 2 at a time and finally 3 of them together with me. It was mildly annoying as I was trying to get to my gate but cute enough I guess. It didnt bother me and it would not have if it was one of my kids. Harmless curiosity...
