A rather lengthy article on CNN that cannot be summarized given the amount of detail in it.
As usual there is likely a time limit as to how long the URL will be active before the article is archived; after that a reader will have to do a search on the website to find it.
A segment of the article is devoted to the UK & the USA.
NOTE: the accompanying pix for the article on the website is one of a little girl; it's not completely well lit, etc.,. Before anyone jumps to the wrong conclusion as to what the mess is on the girl's arm, take a close look at what's in her hand [IMO not a great choice for a pix for such anarticle].
MY choice for an embedded pix is based on Freud. To a small child, the first crisis they face, and attempt a reconciliation of a significant inner conflict, and instinct, in their life, is why in the world anyone would ever want to get rid of the most precious personally crafted gift a child could ever present to mommy and daddy. Lesson #1 re the role of immovable authority in one's life.
While I'm at it, the place of child proofing devices in one's home for even infrequent visits of young children is.......... I am VERY VERY unhappy with my embedded pix on the lack thereof.
We tended towards using a whip and a chair.
Do kids go to the toilet? I've never seen that.......
