Joe and Nikki Have a Daughter Whose Cries Seem Particularly

Joe and Nikki have a daughter whose cries seem particularly irritating.Her cries are high pitched and shrill,they don't follow any sort of pattern or rhythm,and they sound sickly.As responsive parents,they have tried many methods to alter the characteristics of her crying but nothing has worked.Should Joe and Nikki be concerned?

B) yes, because this pattern of crying may be a precursor to sudden infant death syndrome
C) no, because the characteristics of crying are highly individualistic
D) no, because there is little research support for a parent's interpretation of the quality of an infant's cries
