The wording of this question is pretty thought-provoking. They could have asked about parenting 'methods' but instead, they used the word trend, which kind of insinuates that these are not long-lasting ideas. When something is 'trendy' it's usually something without much substance that blew up, and now it's just the cool thing to do. But there's a major emphasis on the word 'now,' because trends change almost every day and who knows? It's been a few hours already since this list was published, some of these could already be out of style. We'll have to pose a new question in a week or so most likely.
