What Can Babies Sleep With? A Guide to Safe Baby Sleep

Understanding what items are safe for your baby to sleep with is crucial to maintaining a safe and comfortable sleep environment. From soft toys to blankets, pacifiers, and more, this comprehensive guide explores what babies can sleep with and what should be avoided to promote safe sleep.

Baby Sleep Essentials

What are the Must-haves in a Baby’s Sleep Environment?

The baby’s sleep area, whether it’s a crib, bassinet, or portable crib, should be equipped with a firm mattress and a tightly fitted sheet. The mattress should fit snugly within the crib frame, with no gaps between the mattress and crib sides. This simple setup reduces the risk of suffocation, entrapment, and Sudden Infant Death Syndrome (SIDS).

What Can Babies Safely Sleep With?

While a bare crib is the safest, there are certain items that babies can sleep with, depending on their age and developmental stage.


The American Academy of Pediatrics (AAP) suggests that pacifiers may be offered at naptime or bedtime, as they have been associated with a reduced risk of SIDS. Ensure the pacifier is clean, and never attach it to strings, cords, or stuffed toys that might pose a choking risk.

What Should Babies Avoid Sleeping With?

Certain items pose risks to a sleeping baby and should always be kept out of the sleep area.

Soft Toys and Blankets

While adorable, stuffed animals, pillows, and blankets can create a risk of suffocation or strangulation. Until your child’s first birthday, it’s best to keep the crib free of these items.

Loose Bedding and Bumpers

Items like loose sheets, quilts, and crib bumpers are also a suffocation risk for babies and should be avoided.

When Can Babies Start Sleeping with Comfort Items?

As your child grows, you may wonder when it’s safe to introduce comfort items, such as a favorite blanket or stuffed animal. After the age of 1, when the risk of SIDS dramatically decreases, it’s generally considered safe to introduce these items.

What Should Babies Wear to Bed?

What Should Newborns Wear to Sleep?

Newborns generally require one layer more than adults would wear in the same environment. A one-piece sleeper or sleep sack can offer comfort without posing risks of suffocation.

How Should I Dress My Baby for Bed Based on Room Temperature?

For a room at 68 degrees, dress your baby in a sleep sack or onesie. At 73 degrees, a short-sleeved onesie or a light sleep sack should suffice. Always remember, the rule of thumb is to dress the baby in one additional layer than an adult would wear.

Do Babies Need to Wear Pajamas?

Pajamas or sleepers are a safe option for infants and provide a comfortable and warm environment for sleep. Make sure the pajamas fit well and are not too loose.

Can Babies Sleep in Just a Onesie?

Yes, a baby can sleep in just a onesie, especially in a warm room. Make sure the onesie is not too loose or too tight.

Should Babies Wear Pajamas Under Sleep Sacks?

Babies don’t necessarily need pajamas under a sleep sack. The sleep sack alone can provide enough warmth. If the room is colder, a light layer under the sleep sack could be necessary.

Sleepwear and Bedding for Babies

How Long Do Babies Use Sleep Sacks?

Babies can use sleep sacks as long as they fit into them and are not able to climb out of the crib. There’s no specific age limit, but most parents transition to toddler bedding around the age of 2 years.

Are Sleeping Suits Safe for Babies?

Yes, sleeping suits or wearable blankets are generally safe for babies as they do not pose the risks of loose bedding.

How Do I Introduce a Blanket to My 1-Year-Old?

Once your baby is 1 year old and the risk of SIDS is significantly lower, you can introduce a small, breathable blanket. Start with short, supervised naps before leaving the blanket with them overnight.

What Bedding is Unsafe for Babies?

Avoid loose blankets, quilts, pillows, bumpers, and soft toys in the crib as these can pose suffocation hazards. Also, avoid plush or sheepskin underlays.

What Can Babies Sleep in Besides a Crib?

Alternatives to a crib include a bassinet or a portable play area. Ensure these meet safety standards and are free from loose bedding or toys.

When Can a Baby Sleep in a Crib Overnight?

Babies can sleep in a crib from birth. However, it’s common for many parents to use a bassinet or bedside sleeper for the first few months for convenience, especially for night feedings.

Where Should Newborn Sleep During the Day?

Newborns should always sleep in the same safe environment, whether it’s during the day or at night – in a crib, bassinet, or portable play area. This helps develop good sleep habits.

Why Are There No Blankets in Bassinets?

Babies should not have loose blankets in their sleep area, including bassinets, as they pose a risk of suffocation. Instead, use wearable blankets or sleep sacks for warmth.
