=In the News:= [] Depression from mom's can hinder the growth of a baby and the development. Infants whose mothers had untreated clinical depression during pregnancy exhibited delayed speech development, reflected in an inability to discriminate non-native language at 6 months, although at months they had developed the ability. Depression is linked to language development. [] Pacifiers may stunt the emotional development of boys. Researchers from the University of Wisconsin-Madison conducted three experiments that tie heavy pacifier use to poor results on various measures of emotional maturity.
