The number of parents or caregivers who sleep with their infants has grown significantly over the recent years.

Such a practice was more prevalent among blacks, where it increased from 21 percent to 39 percent, and Hispanics, where it was 21 percent, up from 13 percent during the same period.
“The disparity in nighttime habits has increased in recent years. Because African-American infants are already at increased risk for SIDS, this trend is a cause for concern”, lead researcher Eve Colson of the Yale University School of Medicine said.
