what age does sids usually occur
Over 4,500 babies in the United States die of SIDS each year. Some babies are more at risk than others. For example, SIDS is more likely when a baby is between 2 and 4 months old, it is more common in boys than girls, and most deaths occur during the fall, winter, and early spring months.
The new study, published in the Annals of Epidemiology, shows: 1  Premature babies died of SIDS up to six weeks later than full-term babies, on average.  Babies born small for their gestational age had a higher SIDS risk than appropriate-sized infants.
