Very young babies vulnerable to sudden death while seated.
Research from the McGill University Health Centre in Montreal shows babies under one month old, in the group of unexplained deaths, were more than seven times as likely to die while seated. The authors point out that their research indicates that the rate of deaths among seated babies is relatively small at just over 3%, and that there are no questions about the necessity or safety of car seats. Instead, extra care should be taken for very young babies in any type of infant seat.
