To the Editor The recently published study by Colson et al1 on the increasing trends of bedsharing highlights the challenges faced by the pediatric community in preventing sudden and unexpected infant deaths (SUIDs). Unfortunately, the accompanying editorial2 by Bergman undermines the message and importance of the article. Bergman cites his work from the early 1990s3 to question epidemiological risk factors, noting that there was no difference between the control group and the “classic sudden infant death syndrome (SIDS)” group. Unfortunately, the Haas et al study3 failed to address the single most important risk factor—the child’s sleep environment.
