IMHO - What a load of tosh the article talks.
Surely if a child knows that he/she is loved and cared for, crying isn't or shouldn't be an issue.
I would say to any mum - trust your instincts, no-one knows a baby better than its mum. Controlled crying didn't work for DD1, but did for DD2 and DS - also worked for Grandson. We only needed to employ the technique for two nights with each of them and they were all very good sleepers after that. We never left them to scream - that's something totally different from crying.
My children ahave grown into well-adjusted, laid back, intelligent young people (apart from DD2 partner issues), and I can see grandson heading that way too, he's so calm it's unbelievable - takes things in his stride.
Comparing what happens to crying babies here with Romanian orphans, who were totally abandond is ridiculous. We're talking about controlled crying in loving families - not leaving our babies to scream and scream until they are very distressed.
The woman responsible for this 'research' and I use the term loosely, has appeared on a number of TV programmes over the past few weeks and doesn't exactly come across as competent.
Additionally, I've never heard of GF, never bought a baby or parenting book as I was determined to do what was best for my babies rather than what some so-called 'expert' told me.
