Sudden infant death syndrome, or SIDS, is the sudden unexplained death of a sleeping baby under 1 year of age. SIDS is the most common cause of death in babies between 1 month and 1 year of age in the United States.
What is the cause?
The exact cause of SIDS is not known. The risk is greater if:
The mother smokes, drinks, or uses drugs before or after the baby is born.
The baby was born premature, or has a brother or sister who died of SIDS.
The baby is a boy.
The baby sleeps face down, sleeps with soft bedding, or is overheated when sleeping.
There is no evidence that immunizations cause SIDS.
How can I help prevent SIDS?
To help prevent SIDS:
Be sure you put your baby to sleep on his or her back.
Have your baby sleep in a crib made just for infants. The mattress should be firm. Donâ€™t let your baby sleep in the same bed with other children or adults.
Do not place soft toys or extra pillows in your baby’s crib.
Do not use loose blankets or other covers in your baby’s crib. If you do use a blanket, tuck it in so that your baby’s face will not be covered. Never let your sleeping baby’s head be covered with a blanket, comforter, or quilt in bed or in a car safety seat.
Breast-feed if you can. Studies show that breast-fed babies have fewer respiratory infections that may increase risk for SIDS.
Try a pacifier. Pacifiers have been linked to a lower risk for SIDS. Do not force your baby to use a pacifier if he refuses.
Do not overheat your baby’s room. The room should be comfortable for an adult wearing light clothing. Your baby should not feel hot to the touch and should never be sweating while asleep.
If you smoke, drink, or use drugs, try to quit, especially if you are pregnant.
If anyone else takes care of your child, be sure they follow these guidelines.
Baby monitors have not been shown to prevent SIDS.
