Reduce the Risk of Sleep-related Deaths

Having a baby comes with a lot of unknowns, but knowing how to safely put your little one to sleep shouldn’t be one of them.

What is SUID?

SUID, or Sudden Unexpected Infant Death, is the sudden death of a baby younger than 1 year that does not have an obvious cause before investigation. SUID deaths include accidental suffocation in a sleep environment which can be due to different mechanisms such as soft bedding, wedging, overlay, or other obstruction of the airway. SUID deaths also include Sudden Infant Death Syndrome (SIDS) which have an unknown cause and other deaths from unknown causes.

In the United States alone, about 3,000 SUID occur each year.

What You Can Do

As a new parent you may get a lot of advice from family and friends. It’s great to have support in your corner, but what was common practice for your parents or grandparents may not be what’s best for the baby—especially when it comes to current safe sleep recommendations.

Learning the risk of SUID, how to avoid it, and educating your family and support system are the best ways to keep your new baby safe. This quick guide will help answer any questions you have and offer tools and resources every step of the way.

What to Know

Alone. Back. Crib.

Easy as ABC:

Safe sleep BY AAP.ORG

Alone

Babies should sleep by themselves, in their own sleep space with nothing and no one else, including other children and pets. Co-sleeping in bed or on a recliner or couch significantly increases the risk of infant sleep-related death due to suffocation. The babies’ sleep space should also be free of toys, blankets, stuffed animals and other soft and plushy items. You can, however, share a room with your baby. In fact, the American Academy of Pediatrics (AAP) recommends room sharing for at least the first 6 months to reduce SUID risk. This means baby sleeps in the same room as the parents, but not in the same bed. Place baby’s crib, bassinet or portable play yard next to or close to your bed.

Back

Infants should always be placed on their back to sleep. Many cultures may consider tummy or side sleeping to be best to reduce choking risk, however, healthy babies can turn their heads if they spit up during sleep. Additionally, babies can clear fluids better when sleeping on their backs because of human anatomy.

Crib

Put baby in a crib, bassinet, or portable play yard with a flat, firm mattress and tight, fitted sheet. That’s all! No bumpers, mobiles, or monitors should be attached to the sleep space. And, of course, no toys or blankets. Couches, armchairs, and adult beds are too soft and can increase risk of suffocation.

Beyond the ABCs

Important practices for safer sleep

The ABCs are a great start, but there are many more ways to help prevent SUID while baby is asleep and awake.

Evidence shows that human milk reduces the risk of SUID and other health problems, as breastfed babies tend to wake up easier than formula-fed babies. If possible, try to breastfeed baby (directly or by pumping) for the first 6 months. The longer you breastfeed, the more protection you provide.
Pacifier use at naptime and bedtime may reduce SUID as it helps keep baby’s airway open. However, never attach a pacifier to baby’s clothing or put it around his or her neck. If a pacifier falls out during sleep, you do not need to put it back in.
Babies have a hard time regulating their body temperature. When a baby gets overly warm during sleep it hinders his or her breathing patterns and makes it harder for him or her to wake up. Keep room temperature between 68-72°F, dress the baby in light, fitted clothing, always keep his or her head and face uncovered, and have good ventilation.
Wearable blankets can keep babies at a comfortable temperature without being loose and posing a suffocation risk.
Swaddling is safe for babies until they can roll over, usually around 3 months old. The swaddle should not be too tight or make it difficult for baby to breathe or move his or her hips.
When baby is awake, tummy time is a great way to sharpen his or her motor development and develop muscles needed for rolling, sitting, and crawling. Start with a short amount of time when you get home with baby, and gradually increase up to 30 minutes a day by the time he or she is 7 weeks old.
A smoke-and-vape-free space during and after pregnancy is crucial for a baby’s health and safety. Secondhand smoke contains toxic chemicals and can damage an infant’s lungs and brain, impacting breathing. Do not allow smoking in your home or car and avoid smoke-filled spaces.
Even devices that claim to prevent tragedies like SUID may be harmful, including heart and breathing monitors. They should not be a substitute for safe-sleep measures. Avoid products that go against safe sleep guidelines.
Good nutrition, no smoking, drug or alcohol use for both mom and dad, and regular medical checkups throughout pregnancy are vital to your baby’s healthy development, and may help prevent your baby from being born with anything that could put him or her at risk for SUID.
Your health care provider knows what is best for you and your baby’s health. Follow their professional advice on everything from vaccines to check-ups and other health issues.

Support and Resources

Establish & Educate Your Village

It takes a village to raise a child. Having outside support can be so helpful after bringing home a little
one. Don’t be afraid to reach out and ask for the physical and mental support you need to
be able to provide the best care for your baby.

Who Can Be Your Village?

Anyone you trust can be part of your support system once baby is home, including extended family, friends, coworkers and neighbors. Health care professionals and recognized organizations can be other reliable sources of support and information when you need it most.

How Can They Help?

Babysitting may be the first thing that comes to mind, however, there are many ways your village can help make your transition into parenthood a little easier or lighten the load if you’re adding to your family.

Extended Family

Extended family members you trust know you and what you need to feel supported. They can help with daily household tasks like dirty dishes and laundry, which can easily pile up when a little one comes home. They can also prepare meals, hold the baby while you shower or rest, and run errands. Having trusted family members can relieve pressure and positively impact your emotional, mental, and physical well-being. You may also feel more comfortable leaving the baby with family.

Friends, Neighbors, Coworkers

Friends can provide much needed camaraderie when parenting feels daunting. This is especially important if you don’t have nearby family or if family support is challenging. Friends can also play the role of family by picking up essential items, watching baby, and offering valuable insight and understanding, especially if they are parents themselves. Friends are also often the first to notice signs of discouragement and suggest seeking professional help.

What Do They Need to Know?

While establishing your village is crucial, it is just as important that they follow the same health and safety guidelines, including being alcohol and drug free. Understand the cultural and generational differences that may vary between members of your support system, and ensure they adhere to the safe sleep practices outlined here.
