OBJECTIVE: The goal of this study was to test the association of mean adult word counts at 32 and 36 weeks’ postmenstrual age in the NICU/Hospital with Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III), cognitive and language scores. It was hypothesized that preterm infants exposed to higher word counts would have higher cognitive and language scores at 7 and 18 months’ corrected age.
