Ensuring your baby’s sleep is safe is one of the most important responsibilities you have as a parent. Sleep safety is something you can control, and it starts with the sleep environment you create for your baby. The latest guidelines and research can feel overwhelming, but don’t worry! We’ve broken everything down into simple, actionable tips you can follow to ensure your baby sleeps safely—every night.

Did you know?

In 1992, the AAP recommended that babies sleep on their backs, which led to a 50% drop in SIDS rates. That’s why it’s so important to follow this guideline, even if other advice from friends and family might suggest differently.

10 tips for safe sleep

These tips are easy to read, remember, and follow. Implementing them will go a long way in protecting your baby during sleep. Here’s your ultimate checklist:

1. Always place your baby on their back to sleep

Why? Placing your baby on their back to sleep has been shown to reduce the risk of Sudden Infant Death Syndrome (SIDS) by 50%. According to the AAP task force recommendations it’s the safest position for your baby to sleep in—no matter whether it’s nap time or bedtime.

Babies who sleep on their stomachs or sides are at a much higher risk of suffocation. Once your baby can roll over on their own, you don’t need to worry about repositioning them at bedtime, but still place them on their back initially.

2. Use a firm mattress with no soft bedding


Why? Soft surfaces like pillows, blankets, and plush toys can cause your baby to suffocate. A firm, flat mattress is essential for safe sleep, nothing else—in your baby’s crib. Inclined sleepers, soft bassinets, or any form of a soft surface for sleeping are a no-go

3. Keep the crib free of pillows, blankets, and stuffed toys


Why? These items can obstruct your baby’s airways and increase the risk of suffocation. A bare crib is the safest option. The AAP’s 2022 recommendations emphasize the importance of eliminating soft sleep products like pillows, bumpers, and soft mattresses. These products increase suffocation risks and are linked to infant deaths. If your baby gets cold, consider a wearable blanket or sleep sack that zips up.

Did you know?

Inclined sleepers were banned in 2022 due to safety risks. These devices are dangerous and do not reduce the risk of SIDS. Always make sure your baby sleeps on a flat, firm surface.

4. Share a room, not a bed

Why? Room-sharing, without bed-sharing, has been shown to reduce the risk of SIDS by up to 50%. Experts recommend that your baby sleep in your room for at least the first six months, but ideally up to a year. However, it’s important to note that bed-sharing is not safe. Always place your baby in their own crib, bassinet, or other approved sleep surface to avoid suffocation risks. This way, you can respond quickly to their needs without the risks associated with bed-sharing.

5. Keep the room at a comfortable temperature

Why? Overheating is a significant risk factor for SIDS. If you’re comfortable in a T-shirt and light pants, your baby should be too. Avoid thick blankets, hats, or excessive clothing. Experts recommend keeping the room temperature between 68°F and 72°F (20°C and 22°C).

Tip: If you’re unsure if your baby is too warm, feel the back of their neck—if it feels hot, they may be overheated.

6. Offer a pacifier at nap time and bedtime

Why? Offering a pacifier during sleep times has been shown to reduce the risk of SIDS by up to 90%. If you’re breastfeeding, it’s fine to introduce a pacifier once breastfeeding is well-established (typically around 3-4 weeks). Don’t worry if the pacifier falls out during sleep; there’s no need to replace it.

7. Avoid exposure to smoke

Why? Babies who are exposed to tobacco smoke—whether in utero or after birth—are at a higher risk of SIDS. Make sure your home and car are smoke-free, and ensure that no one smokes around your baby. The harmful chemicals in smoke can affect a baby’s respiratory and cardiovascular health, contributing to the risk of sleep-related incidents.

8. Use an appropriate sleep sack

Why? Sleep sacks or wearable blankets keep your baby warm without the dangers of loose bedding. Unlike blankets that can slip over your baby’s face and obstruct their airway, a sleep sack fits snugly around the baby’s body and leaves their head and neck free. Choose one that’s the right size for your baby and the temperature of the room.

9. Don’t use baby sleep positioners or wedges

Why? Despite some products claiming to reduce the risk of SIDS, the AAP warns against using sleep positioners or wedges. These products do not prevent SIDS and may increase the risk of suffocation. The safest option is a flat sleep surface with no extra products inside the crib.

10. Keep your baby’s head uncovered

Why? Babies can easily overheat if their heads are covered. Avoid hats or any coverings during sleep. Instead, dress your baby in comfortable sleepwear that’s appropriate for the temperature in the room. Use a breathable fabric like cotton, which will help regulate your baby’s body temperature.

How to keep up with safe sleep guidelines

Safe sleep practices evolve, so it’s essential to stay updated on the latest research and recommendations. The AAP regularly publishes updated guidelines on safe sleep practices, and it’s important to check these resources periodically, especially as your baby grows.

While following the 10-second tips above is a great foundation, make sure you stay proactive about safe sleep by checking for product recalls, learning about any new research, and following healthcare professionals’ advice.

Some helpful ways to stay informed include:

  • Subscribing to the AAP’s newsletter or blog for updates
  • Keep in touch with your pediatrician and ask questions about safe sleep practices. 

The new responsibility of being a parent can feel overwhelming at times. By prioritizing safety and adhering to recommended guidelines, you can provide your little one with the best possible start in life. These simple, research-backed tips will ensure  your baby sleeps safely—giving you peace of mind as they grow and develop. Sweet dreams for you and your little one!
