The article is shocking, and saddening.
There are so many errors and opinions in it - nothing is backed up with evidence, and what 'evidence' there is, is misunderstood.
Who are the developmental psycholgists concerned with this ? Apparently there are 'many' who are 'worried' about it.
"Dr Sears even claims that allowing a baby to cry for too long can cause them brain damage." Leaving babies to cry for too long is harmful....this is not controversial. I don't think anyone would say that very occasional lengthy crying because of issues beyond the parents' control is brain damaging, but lengthy crying does affect a baby biochemically, and persistent neglect of crying does change the baby's brain....not in the least a new idea and not something anyone, least of all a doctor, should be dismissing.
Sears does not claim that all the bells and whistles of 'attachment parenting' are 'essential' to attachment, either. She (author) goes in to dismiss this: "proper bonding is supposed to nurture better emotional health and make the child more intelligent, calm, secure, confident, empathic and independent." Eh? We know parent-child bonding does all that stuff!
Rubbish and annoying rubbish, too :( :(
