1. on their backs
   on their bellies
2. on their sides

Placing a baby to sleep on his or her back is one of the best things you can do to reduce the baby's risk of SIDS. The American Academy of Pediatrics manages a campaign called "Back to Sleep" to remind parents and caregivers that babies should always be placed on their back in a crib, and never face down.

1. keep moving them back onto their back
   use a sleep positioner
2. leave them alone

While you should always put a baby to sleep on their back, some babies will eventually start to roll over onto their belly or side. Once a baby can roll on their own, it's OK to leave them that way, and there's no need to keep repositioning them onto their back all night -- but you should still put them on their back when you first put them down.

1. sleep positioner
   crib bumpers
2. neither

The American Academy of Pediatrics warns parents not to use either a sleep positioner or a crib bumper. Both are more likely to harm your baby than to protect them, and crib bumpers in particular are a serious suffocation hazard.

1. pillow
   stuffed animals
2. neither

Nothing goes into a crib except for a baby. Children under one year of age are at a serious risk of suffocation or SIDS if a stuffed animal or pillow is used in the crib.

1. sleep sack
   thin blanket
2. thick quilt

Blankets don't belong in cribs, as they could cause the baby to suffocate. Instead, use a swaddle or sleep sack to wrap your baby up safely and keep them warm and comfortable.

1. in bed with Mom and Dad
   in a crib in the parents' room
2. in their own room

The safest place for babies to sleep is in the same room as their parents, but in their own crib. Sharing a bed with Mom and Dad puts baby at risk for SIDS or suffocation.

1. taking a bottle to bed
   taking a pacifier to bed
2. having a teether in bed

Doctors aren't 100 percent sure why it helps, but there is evidence that giving a baby a pacifier can reduce the risk of SIDS. Put the pacifier in the baby's mouth when you put him to bed, but don't worry about replacing it over and over again if it falls out during the night.

1. parents who smoke around the baby
   parents who smoke, but not around the baby
2. both

Any exposure to cigarette smoke, even if you don't actually smoke around the baby, is linked to an increased risk of SIDS. Protect your baby by banning smoking in your home, and come up with a plan for both parents to quit smoking to keep your child as safe as possible.

1. vaccines don't affect the risk of SIDS
   vaccines increase risk of SIDS
2. vaccines reduce risk of SIDS

Turns out, getting your children vaccinated does more than protect them from disease; it also reduces their risk of SIDS by as much as 50 percent.

1. a firm mattress
   a soft mattress
2. a firm mattress with a soft pillow topper for comfort

Soft mattresses or bedding pose suffocation or SIDS risk. Protect your child by placing them on a firm mattress topped with only a well-fitted sheet.

   50 percent
2. 100 percent

Placing a baby on their stomach or side to sleep doubles their risk of SIDS compared to placing them to sleep on their back. There's simply no better way to prevent SIDS, based on what we currently know about the condition, than to follow the advice of the Back to Sleep campaign.

1. babies can be placed on their stomachs for short naps only
   babies can be placed on their sides if you use a pillow so they can't roll over
2. babies used to sleeping on their backs are even more likely to die than other babies if they sleep on their stomach

When it comes to placing your baby to sleep on his back, there should be no exceptions, even at daycare or other people's homes. A baby who is used to sleeping on his back is 18 times more likely to die of SIDS if he is placed on his side or stomach for the odd nap.

1. no impact
   increases it
2. reduces it

Breastfeeding cuts the risk of SIDS by as much as 50 percent, but there's still plenty that bottle-feeding families can do to protect their children -- including using a safe sleeping environment, avoiding all tobacco smoke and giving the baby a pacifier at bedtime.

1. much cooler than adults
   about the same as adults
2. much warmer than adults

Many people worry about infants getting cold, but babies actually need to be in a space that would be comfortable for an adult. Bundling a baby up excessively or setting the thermostat too high is actually linked to an increased risk of SIDS.

1. breathing monitors
   sleep positioners
2. neither

Both the FDA and the CDC warn that there are no products on the market proven to prevent SIDS. Instead of splurging on these products that claim to cut risk, use techniques that the experts give for free, like avoiding tobacco and creating a safe sleep environment.

1. babies with colds
   babies with diagnosed upper airway disorders
2. babies who were born prematurely

Some people place babies on their bellies to sleep because they are afraid the baby will choke. The truth is, sleeping on the back does not increase the risk of choking aspiration, according to the American Academy of Pediatrics. The only time a baby should ever be placed on his stomach to sleep is if he has a diagnosed upper airway disorder -- not a cold or virus -- and the doctor tells you that he should be placed on his stomach. Otherwise, it's Back to Sleep all the way to prevent SIDS.

1. give them more tummy time while awake
   have them wear more hats
2. buy them a baby wig

A flat spot on the head usually means the baby is spending too much time on his back during the day. Keep placing him on his back to sleep, but give him as much tummy time as possible during the day to reduce the risk of flat spots.

1. swing
   car seat
2. neither

There is no safe alternative to placing a baby flat on his back in a crib when it comes to reducing SIDS risk. Car seats, strollers and slings are not safe sleeping spots, especially for babies under four months old.

1. when you are having trouble getting him to sleep
   when you are napping with him
2. never

Soft spots like couches pose a serious risk for SIDS, and should never be considered a safe sleeping spot for babies.

1. 20 percent
   half
2. 90 percent

A staggering 90 percent of all SIDS cases occur in babies younger than six months. Of course, that doesn't mean you are safe after the baby hits the seven-month milestone -- the remaining ten percent occur in children between six months and one year old.

1. 1 percent
   10 percent
2. 30 percent

Despite repeated warnings from pediatricians and other experts, around 30 percent of babies are still placed on their stomachs at bedtime, putting them at a serious risk for SIDS.

1. bed sharing
   pillows in the crib
2. a cat in the home

Around 70 percent of infants who die of SIDS were sharing a bed with someone. Bed sharing is extremely dangerous to babies, due to the risk of suffocation, especially if someone rolls over on the child.

1. abuse
   illness
2. SIDS

Stories about abuse may get all the media attention, but SIDS is by far the largest killer of otherwise healthy infants, so taking steps to reduce your risk is one of the smartest steps you can take as a parent.

1. It's safest to place the crib near a radiator to keep baby warm at night.
   Set the thermostat to 68 degrees for infant sleep safety.
2. It's best to bundle your baby up so he doesn't catch a chill while sleeping.

Keeping your baby too warm at night increases his risk of SIDS. Remember that babies should sleep at approximately the same temperature as adults, around 68 degrees F, so a pair of pajamas and a sleepsack should be sufficient unless the temperature in the home is frigid.

1. giving birth before the age of 20
   giving birth over age 40
2. being a heavy sleeper

Certain maternal factors are associated with an increased risk of SIDS, including giving birth before the age of 20, smoking, taking drugs, drinking alcohol or failing to obtain adequate prenatal care.

1. boys
   girls
2. both are equally vulnerable

While no one is exactly sure why, boys are slightly more vulnerable to SIDS than girls. SIDS also has a genetic component, which means that if one member of a family dies of SIDS, other members are more vulnerable to SIDS than families with no SIDS-related deaths.

1. being of Caucasian descent
   being of African-American or Native American descent
2. being born prematurely

Certain babies are more susceptible to SIDS than others, including babies born prematurely and those of African-American or Native-American descent in the U.S.

1. stricter prenatal drug testing
   reduced lead in gasoline
2. Back to Sleep campaign

The American Academy of Pediatrics launched the Back to Sleep campaign, encouraging parents to put babies to sleep on their backs, in 1994. Since then, the rate of SIDS deaths has been cut in half!

1. 250
   2,500
2. 25,000

Around 3,500 babies still die of SIDS each year, as of 2016. It's not possible to know, however, if some of these deaths are classified incorrectly, due to incomplete diagnosis or sensitivity to grieving families.

1. twelve hours
   one hour
2. there is no minimum recommended time

If possible, mothers and babies should have a minimum of one hour "skin-to-skin care" shortly after birth, when the mother is stable and awake. This is recommended by the American Academy of Pediatrics as a means to help prevent SIDS.
