See below from Dr Markham in regards to Ferber. This is just an excerpt there is more in the article.

With a very determined and resourceful baby, this crying can go on all night, but more usually the baby will become exhausted and fall asleep after a few hours. When he reawakens later in the night, the process is repeated. Often the next interval of crying is shorter, either because the baby has given up on the parent staying, or because he is exhausted. Sometimes it is longer, because the baby is re-energized (or an extremely determined person, who will someday accomplish great things by virtue of his strong will.) Usually, though, the crying diminishes on subsequent nights, as the baby learns not to expect the parent to stay with him.

While listening to their baby cry is hard on parents (not to mention the baby), most babies do eventually give up calling for their parents, and sleep. Because they do not yet talk, and live so completely in the moment, we do not hear from them the next morning how they felt about the experience.

However, even when parents are consistent, this approach does not work on all children. Some babies are still crying on the seventh night in a row. It is not uncommon for babies to get an ear infection in the middle of it (from the congestion caused by the crying); it is recommended that the Ferberizing be discontinued during the round of antibiotics that follows, to be re-initiated later. In addition, since any change in the routine (a brief illness, a trip to Grandma's) requires parents to respond to the baby's cries and then to repeat Ferberizing on another night, this process must be endured repeatedly by both baby and parents.

There are many studies claiming that repeatedly leaving babies to cry it out is a risk factor that predisposes kids to permanent brain changes and mental health issues in later life. However, advocates of Ferberizing say that because the parent keeps returning to the child's room, this offers the child reassurance that he has not been abandoned, and therefore keeps the experience from traumatizing the baby in the way that just letting them "cry it out" does.

The most recent claim that letting kids "cry it out" without reassurance may cause lasting damage is the finding that when a baby is left to cry alone, her cortisol level shoots up, indicating distress. That's not surprising. What is surprising is the research study* showing that on subsequent nights -- even when the baby is put into bed and does not cry -- her cortisol level still shoots up. Researchers interpret this as an indication that she is distressed. So why doesn't she cry? Because she has been "trained" -- she knows that no one will come.

*Middlemiss, Wendy et al. "Asynchrony of mother–infant hypothalamic–pituitary–adrenal axis activity following extinction of infant crying responses induced during the transition to sleepEarly Human Development, Volume 88 , Issue 4, 227 - 232

Margot Sunderland's The Science of Parenting cites many studies that Sunderland claims support her view that repeated, sustained crying without adult reassurance causes babies' brains to develop less than optimally. My perusal of her sources showed some that probably should not be used to support her claim because they studied more extreme circumstances. But many of the studies seem credible.

Harvard Researchers who examined emotional learning, infant brain function and cultural differences claim that babies who are left to cry themselves to sleep suffer long-lasting damage to their nervous systems. The researchers claim that this makes these children more susceptible in later life to anxiety disorders, including panic attacks. The incidence of anxiety disorders has increased dramatically in recent years, but I personally don't think this is necessarily correlated to the practice of letting children "cry it out." My own view is that such a susceptibility could be caused by many aspects of childhood in 21st century North America and would need to be triggered by later trauma to play out.

So the question is whether the intermittent parental reassurance (but refusing to pick up the pleading baby) as specified by the Ferber method protects the child from the risks of just letting him "cry it out." Some anti-Ferber folks claim that the parent coming into the room and ignoring the baby's distress might actually increase the trauma by undermining the baby's trust in the parent.

It's hard to evaluate research in this area because there are so many other factors (many of which are arguably more important) in how babies develop. However, it is well-documented that sustained, uncomforted infant crying causes increased heart rate and blood pressure, reduced oxygen levels, elevated cerebral blood pressure, depleted energy reserves and oxygen, and cardiac stress. Cortisol, adrenalin and other stress hormones skyrocket, which disrupts the immune system and digestion. It's a reasonable guess that if this is repeated over time, these babies would build a slightly different brain, more prone to "fight, flight or freeze."

We know that with adults, even one panic-inducing experience like a car accident or mugging that causes an extreme stress response can have ongoing stress effects for years. Since babies' heart rates and blood pressure soar during Ferbering, I don't think there can be any doubt that sleep training without parental comfort causes the experience to be indelibly etched on the memory, much as any panic situation can evoke strong feelings years later. That the memory is sensory and preverbal just gives it more power, as it cannot be adequately processed.

So there are a growing number of critics who see Ferberizing as barbaric. Their position can be summarized as follows:

Dr Markham is one woman with one pov.
There are many other views re cortisol levels, crying, etc.

And again I still don't see how you could 100% know that someone having panic issues, attachment issues, later is caused by crying during infancy.
