A new study suggests that infants left to CIO — "cry it out" or cry themselves to sleep will not suffer any emotional, behavioral or parental attachment problems, Today.com reported.
Researchers in Australia studied infants 6 months through 16 months and found that CIO did not produce any more signs of stress in the babies than a "gentler" method, according to the study published Tuesday in the journal Pediatrics.
The lead author of the study, Michael Gradisar, an associate professor and clinical psychologist at Flinders University in Adelaide, Australia, said "graduated extinction was better in reducing the number of times the infants woke during the night, as well as the amount of time they spent awake during the night."

The new study adds to existing research showing that children sleep better when parents adopt the extinction method, said Dr. Marc Weissbluth, a professor of clinical pediatrics, emeritus, at Northwestern University's Feinberg School of Medicine.
