Hi there! Speaking for myself, the few postings I've posted are of my kids. Except for the last posting, permission was granted by the parent. Sometimes the kids will ask me to take a photo of them. Those which I take without the permission of parents are kept in my own personal album.
Oops, have just re-read your last question. Admittedly, I asked for permission to take but not to post. I guess some of us, in wanting to share pictures of the beauty of the kids, we forget the considerations of their parents. I shall definitely keep that in mind for all my future postings.
