The threshold, latency, and peak fundamental frequency (basic pitch) o
f crying were sensitive to the subclinical effects of prenatal alcohol
exposure through the first month of postnatal life. Whereas infants w
ith prenatal alcohol exposure showed a lower cry pitch and higher cry
threshold at 2 days of age, higher pitched cries, typical of nervous s
ystem insult, were evident at 14 and 28 days. A longer latency was als
o evident at 14 days.
