I'm surprised that this sort of study, with a sample size of only 225, was
published. It seems like quite a stretch to extrapolate that kids are not
emotionally affected and their relationships with their parents are not
negatively affected with such a small sample size....Perhaps it
would be more beneficial for parents to change their expectations (leading to
less depression) than for the babies to change their behavior.
I could have told you that for free!but glad to hear the study backs up
what we sleep deprived moms already know!
