The reporter read the article, put his spin on it and sold a newspaper.
The information and conclusion in the studies stays relevant, and it's fairly widely accepted that there are alway people that fall outside the norm when studies are conducted.
For example, birds fly north/south in winter/summer depending on the bird and which side of the equator your on. A few select birds don't, they might fly east/west or not move at all. These are often referred to as aberrant genotypes and are essential to a species survival if there's a catostropic event that wipes out the main flock. That's not a good v's bad observation, it just is.
The studies referred to concluded that child care is not harmful - based on the children surveyed and studied. You assert your child was - and that is to be expected that someone will not be an 'average' person AND THAT IS OKAY TOO. The blanket title is a bit unfortunate.
The upshot is that working mothers often get derided and bullied and sneered at for abusing, neglecting their kids, for being money hungry, part time parents and for having their kids raise by other people. Just for once a study and an article disproves the smear campaign and I for one applaud it.
That doesn't mean I don't feel sympathy for your dd and I understand you did the very best you could at the time.
