Safe Sleep Tips for Babies: Everything Parents Need to Know

We have gathered answers to the most frequently asked questions about babies' sleep to provide parents with essential guidance. This resource covers topics such as how much sleep newborns need, the safest sleeping positions, and ways to reduce the risk of Sudden Infant Death Syndrome (SIDS). It also addresses important questions like when to introduce tummy time, whether it is safe for babies to fall asleep while feeding, and the appropriate age for sleep training. Additionally, we provide information on using sleep sacks, introducing a pillow, and creating a safe sleep environment. With expert-backed advice, this guide is designed to help parents make informed decisions about their baby’s sleep.

How Much Should a Newborn Sleep by Age? 

Newborns need a significant amount of sleep to support their rapid development and growth. Here’s a breakdown of sleep patterns by age:

• Newborns (0-1 Month): Newborns typically sleep 14-17 hours a day. This sleep is spread across both day and night in short stretches of 2-4 hours. Their internal clock isn’t developed yet, so sleep patterns are irregular.
• 1-2 Months: Babies begin to sleep slightly longer at night, but they still need 14-16 hours of total sleep daily. Daytime naps remain frequent.
• 3-6 Months: Around this age, sleep becomes more structured, with babies sleeping 10-12 hours at night (with interruptions for feedings) and taking 3-4 naps during the day.
• 6-12 Months: Most babies sleep 10-12 hours at night with 2-3 naps during the day, totaling 12-15 hours.

Establishing a consistent bedtime routine can help develop healthy sleep habits as early as a few weeks old.

Can I Let My 1-Week-Old Sleep Through the Night? 

No, it’s not recommended to let a 1-week-old sleep through the night. Newborns have small stomachs and need frequent feeding to maintain adequate nutrition and hydration. Typically, they should be fed every 2-3 hours, even overnight. Allowing a newborn to sleep too long without feeding can lead to dehydration and slower weight gain. Once your pediatrician confirms healthy weight gain and development, you may extend nighttime sleep gradually.

When to Start Tummy Time? 

Tummy time can begin as early as the first day home from the hospital. Start with short sessions of 1-2 minutes, 2-3 times daily. Gradually increase the duration as your baby grows stronger and more comfortable. By 3-4 months, aim for a total of 20-30 minutes of tummy time daily. This activity helps develop neck, shoulder, and upper body strength, which are essential for milestones like rolling over and crawling.

What Happens if You Don’t Do Tummy Time? 

Skipping tummy time can delay your baby’s physical development. Potential consequences include:

• Flattened Head Syndrome (Positional Plagiocephaly): Without tummy time, babies spend too much time on their backs, which can lead to a flat spot on the head.
• Weakened Neck and Upper Body Muscles: Tummy time strengthens muscles needed for lifting the head, rolling over, and eventually sitting up.
• Delayed Motor Skills: Milestones like crawling and walking might take longer to achieve.

If your baby dislikes tummy time, try placing them on your chest or using toys for engagement.

Does Feeding Count as Awake Time? 

Yes, feeding is part of a baby’s awake time. Awake time includes all activities between naps, such as feeding, diaper changes, and interaction. For newborns, awake time may only last 45 minutes to an hour before they’re ready to sleep again. Keep this balance in mind to avoid overtiredness.

What is the 40-Day Rule for a Baby? 

The "40-day rule" is a traditional practice observed in many cultures. It suggests mothers and newborns stay at home or minimize outings for the first 40 days postpartum. The focus is on bonding, recovery for the mother, and protecting the baby’s fragile immune system. While not a medical requirement, many families find this practice helps establish a stable routine and reduces exposure to germs.

Is it OK if Baby Falls Asleep While Feeding? 

Yes, it’s common and normal for babies to fall asleep while feeding, especially during the newborn stage. Feeding is a comforting and relaxing activity. However, it’s important to ensure your baby gets enough milk during each session. If they fall asleep before finishing, gently wake them by stroking their cheek or burping them. Over time, as sleep and feeding patterns stabilize, this behavior often decreases.

When to Start Sleep Training? 

Sleep training is typically recommended between 4-6 months. At this age, babies are developmentally ready to sleep for longer stretches and self-soothe. Common sleep training methods include:

• Cry-It-Out (CIO): Allowing the baby to cry for increasing periods before comforting them.
• Gentle Methods: Gradually reducing parental involvement in falling asleep, such as the "Ferber Method."

Consistency and patience are key to successful sleep training. Always consult your pediatrician before starting.

What is the 15-Minute Rule for Babies? 

The 15-minute rule often refers to sleep or settling techniques. For example:

• Self-Soothing: Allowing the baby 15 minutes to settle and fall asleep before intervening.
• Crying Intervals: Waiting 15 minutes during nighttime wake-ups to see if the baby can return to sleep independently.

This rule encourages self-soothing but should be adjusted based on your baby’s age and temperament.

What is the Safest Way for a Baby to Sleep? 

The safest way for a baby to sleep follows the ABC guidelines:

• Alone: Babies should sleep alone in their crib or bassinet, without blankets, toys, or pillows.
• Back: Always place babies on their back for sleep to reduce the risk of Sudden Infant Death Syndrome (SIDS).
• Crib: Use a firm mattress with a fitted sheet in a safety-approved crib or bassinet.

Room-sharing (not bed-sharing) is recommended for the first 6-12 months.

What is the 5-3-3 Rule for Babies? 

This sleep rule isn’t universally recognized but often relates to balancing awake and sleep time:

• 5 Hours Morning Wake Time
• 3 Hours Midday Nap
• 3 Hours Evening Wake Time

It’s a flexible guideline to help structure a baby’s schedule, particularly for older infants transitioning to fewer naps.

What Are Three Unsafe Things to Do for a Sleeping Infant?

1. Co-Sleeping: Sharing a bed increases the risk of suffocation and SIDS.
2. Using Soft Bedding: Pillows, blankets, and stuffed toys can obstruct breathing.
3. Placing Baby on Their Stomach: Sleeping on the stomach is associated with a higher risk of SIDS.

What Not to Do When Putting a Baby to Sleep?

• Avoid Overheating: Dress your baby in light layers and keep the room temperature comfortable (68-72°F).
• Don’t Use Inclined Sleepers or Positioners: These products can lead to suffocation.
• No Loose Bedding: Stick to a firm mattress and fitted sheet.

What is SIDS?

SIDS, or Sudden Infant Death Syndrome, refers to the unexplained and sudden death of an otherwise healthy infant, typically under 1 year of age, during sleep. It is also called “crib death” because it often occurs while babies are in their cribs. Despite extensive research, the exact cause of SIDS remains unknown, but it is believed to result from a combination of factors related to an infant’s physical condition and their sleeping environment.

When Does SIDS Most Likely Occur? 

SIDS is most likely to occur between 1-4 months of age, with the peak risk at 2 months. The risk decreases significantly after 6 months but is not entirely eliminated until 12 months.

What Are the Warning Signs of SIDS? 

SIDS has no clear warning signs. However, risk factors include:

• Prematurity or low birth weight
• Exposure to smoke during pregnancy or after birth
• Unsafe sleep environment (e.g., soft bedding, stomach sleeping)

Preventative measures focus on creating a safe sleep environment.

Are Sleep Sacks Safe? 

Yes, sleep sacks are safe and recommended as a wearable blanket alternative. They eliminate the risk of loose bedding while keeping the baby warm and cozy. Choose the correct size to ensure it’s not too loose around the neck and arms.

What is the Best Age for a Sleep Sack? 

Sleep sacks can be used from the newborn stage through toddlerhood. Many parents use them until the child transitions to a regular blanket around 2-3 years old. For newborns, swaddles are often used before switching to sleep sacks.

What to Use Instead of a Sleep Sack? 

If your baby dislikes sleep sacks, consider:

• Swaddling: For newborns who are not yet rolling over.
• Footed Pajamas: These provide warmth without the need for loose blankets.
• Thermal Sleepers: Lightweight, breathable alternatives for warmer climates.

When to Give Baby a Pillow? 

Pillows should not be introduced before 18-24 months. Using a pillow too early increases the risk of suffocation and SIDS. After 2 years, use a firm, small pillow designed for toddlers.

What Position is Safest for a Baby to Sleep? 

The safest position for a baby to sleep is on their back. This position significantly reduces the risk of SIDS and is recommended for all sleep, including naps and overnight.
