Hello, I don't think crying for three hours in normal or healthy for anyone.... Here are few reasons (besides instinct) I oppose CIO
I would like to share some research on the physical/chemical effects prolonged crying has on babies, Science tells us that when babies cry alone and unattended, they experience panic and anxiety. Their bodies and brains are flooded with adrenaline and cortisol stress hormones. Science has also found that when developing brain tissue is exposed to these hormones for prolonged periods these nerves won’t form connections to other nerves and will degenerate. Is it therefore possible that babies who endure many nights or weeks of crying-it-out alone are actually suffering harmful neurologic effects that may have permanent implications on the development of sections of their brain.
Infant developmental specialist Dr. Michael Lewis presented research findings at an American Academy of Pediatrics meeting, concluding that “the single most important influence of a child’s intellectual development is the responsiveness of the mother to the cues of her baby.”
Researchers have found babies whose cries are usually ignored will not develop healthy intellectual and social skills.
I know that this culture is not as supportive of attatchement parenting but you can help lead the way!
I have found the Willia Sears M.D. has written some great books that are very in tune with instinct and foster the growth of secure children.
good luck and please don't feel obligated to make your child cry it out
