A new study shows that at 2 to 4 weeks of age male infants are easier to arouse than females during quiet sleep, and by 2 to 3 months of age there are no significant gender differences in arousability. The results suggest that the increased rate of sudden infant death syndrome (SIDS) in males may not reflect a pre-existing vulnerability involving arousal responses.
