When Can a Baby Sleep With a Blanket, Pillow or Lovey?

The short answer is not before the first birthday. Every federal and professional source on infant sleep in the United States gives the same instruction for the first year: a firm, flat mattress, a fitted sheet, the baby on their back, and nothing else in the sleep space. That "nothing else" covers the three things parents most want to add, which are a blanket, a pillow and a small soft toy or lovey.

The longer answer is more useful, because the rule is not arbitrary and it does not loosen at the point most parents expect it to. A baby who can roll and lift their head looks capable of pushing a blanket away. The death-review data suggest that is exactly the age at which objects in the crib become the larger share of the risk.

What the agencies say, word for word

The American Academy of Pediatrics. The AAP's 2022 policy statement on sleep-related infant deaths, by Moon, Carlin and Hand for the AAP Task Force on SIDS and the Committee on Fetus and Newborn, lists the elements of a safe sleep environment as back sleeping, a firm, noninclined sleep surface, room sharing without bed sharing, and avoidance of soft bedding and overheating. HealthyChildren.org, the AAP's site for parents, spells out what soft bedding covers: pillows and pillow-like toys, quilts, comforters, mattress toppers, non-fitted sheets, blankets, toys, bumper pads and related products that attach to crib slats or sides. It gives the reason as a risk of entrapment, suffocation or strangulation. A footnote on the same page sets the age range: unless stated otherwise, the recommendations are for babies up to 1 year of age.

The NICHD's Safe to Sleep campaign. The National Institutes of Health campaign is the most specific of the four, and it is the one that names loveys. Its list of dangerous items sorts them by why they are dangerous: soft or squishy items such as pillows, stuffed toys and crib bumpers, items that go under or over the baby such as comforters, quilts, blankets and positioners, and non-fitted items "even if lightweight, small, or 'tucked in'", with loveys, cloths, non-fitted sheets and tucked-in blankets given as the examples. Weighted blankets and weighted swaddles get their own category. The campaign also says babies should be placed on their backs for every sleep until they are 1 year old.

The Consumer Product Safety Commission. The CPSC's safe sleep page explains the mechanism in one sentence: many young babies cannot lift their heads to pull away from soft objects that can pose a suffocation risk, such as bumpers, blankets, pillows and sleep positioners. Its list of don'ts opens with not adding pillows or blankets to a baby's sleep space and not using weighted blankets or weighted swaddles. Its summary line is that the safest way for a baby to sleep is flat on their back without pillows, blankets or toys in the sleep space.

The CDC. The Centers for Disease Control and Prevention says to keep soft bedding out of the baby's sleep area and lists blankets, pillows, bumper pads and soft toys.

Four agencies, one list. None of them carves out a small lovey, a thin muslin blanket or a blanket tucked in at the foot of the crib, which was once common advice and is now on Safe to Sleep's unsafe list by name.

What the death data show

Two studies in Pediatrics explain why soft items sit at the top of the list rather than somewhere in the middle.

Soft bedding is the largest single cause of infant suffocation in bed. Erck Lambert and colleagues, working with the CDC's Division of Reproductive Health, analysed the Sudden Unexpected Infant Death Case Registry for 2011 to 2014. They note that unintentional suffocation is the leading cause of injury death in infants under 1 year in the United States, and that 82 percent of those deaths are attributed to accidental suffocation and strangulation in bed. Of the registry's sudden unexpected infant deaths, 14 percent were classified as suffocation. Within that group, soft bedding was the mechanism in 69 percent, ahead of overlay by another person at 19 percent and wedging at 12 percent. The median age at death in the soft-bedding group was 3 months. Those deaths happened most often in an adult bed (49 percent) and with the infant prone (82 percent), and in 34 percent a blanket or blankets were obstructing the airway.

Objects matter more as babies get older, not less. Colvin, Moon and colleagues looked at 8,207 sleep-related infant deaths from 24 states between 2004 and 2012, drawn from state child death review reports, and compared infants aged 0 to 3 months with infants aged 4 months up to the first birthday. An object was found in the sleep environment in roughly a third of all deaths. In the older group the share was higher, 39.4 percent against 33.5 percent. Blankets (24.5 percent) and pillows (17.6 percent) were the only objects present in more than 1 in 10 deaths, and older infants were significantly more likely to have died with a blanket (26.8 against 23.5 percent) or a stuffed toy (2.4 against 1.2 percent) in the space. Older infants were also more likely to have been placed on their back or side and then found on their stomach, 18.4 percent against 13.8 percent.

The authors' conclusion is direct. For younger infants the predominant risk factor was bed sharing. For older infants it was rolling into objects in the sleep area. Rolling from back to front typically starts around 4 months, and they suggest that many of the older infants rolled into blankets, bags or stuffed animals and could not get free.

That is the finding that answers the question parents actually ask. A 6-month-old who rolls and lifts their head is not past the risk of a lovey in the crib. On this evidence, that baby is in the age group where objects make up a larger share of deaths than they do in newborns.

The 2022 AAP statement gives the overall scale: about 3,500 infants in the United States die each year of sleep-related causes, including SIDS, ill-defined deaths and accidental suffocation and strangulation in bed, and the rate has been stagnant since 2000. These are population figures from death reviews. They describe where risk concentrates, not what will happen to any one baby, and no single change to a crib can promise an outcome.

The products the federal rules already restrict

Some of what parents might put in a crib is not merely advised against. It has been regulated.

Infant cushions and bean-filled infant pillows are banned. Under 16 CFR 1500.18(a)(16), any article known as an infant cushion or infant pillow is a banned hazardous substance if it has a flexible fabric covering, is loosely filled with a granular material such as polystyrene beads or pellets, is easily flattened, can conform to the body or face of an infant, and is intended or promoted for children under one year of age. The Commission's findings in the same section say it considered warning labels and a performance standard and rejected both, concluding that no label would significantly prevent the hazard and that no feasible standard existed.

Nursing pillows now carry a federal no-sleep warning. The CPSC's nursing pillow standard, 16 CFR part 1242, applies to nursing pillows manufactured after April 23, 2025. It requires the package to warn, at a minimum, "Do not use for sleep" and "Do not use in sleep products like cribs, bassinets, or play yards." HealthyChildren gives a nursing pillow and a lounger-style baby nest as its examples of products not to use for sleep.

Padded crib bumpers are banned outright. Congress removed padded bumpers and inclined sleepers from the market in 2022, which is covered in what the Safe Sleep for Babies Act banned.

Weighted sleep products are named by every agency. The AAP, the CPSC and Safe to Sleep all say not to use weighted blankets, sleepers or swaddles on or near a sleeping baby.

The ordinary flat baby blanket and the small plush lovey are not banned products, and they are sold legally for daytime use, tummy time on the floor and the pram walk. The guidance is about where they go, not whether they may be owned.

Keeping a baby warm without a blanket

The reason most parents reach for a blanket is warmth, and the agencies answer that directly.

A wearable blanket replaces the loose one. HealthyChildren says that if you are worried about the baby getting cold, dress them in layers of clothing or use a wearable blanket. Safe to Sleep gives the same instruction: a wearable blanket or an extra layer of clothing keeps the baby warm without adding items to the sleep area.

One layer more than an adult. HealthyChildren's rule of thumb is to dress the baby in only one layer more than you are wearing. Overheating is a separate risk factor in its own right, and Safe to Sleep lists sweating, flushed or red skin and a chest that feels hot to the touch as signs a baby is too hot. A hat comes off indoors.

A swaddle is a blanket with an expiry date. A wrap that holds is a sleep garment. A wrap that has come loose in the crib is a loose blanket. The cut-off tied to the first signs of rolling, and the move to an arms-out sleep sack, is set out in when to stop swaddling.

If a baby is brought into an adult bed to feed or be comforted, HealthyChildren's advice is to put them back in their own sleep space before the adult goes to sleep, and to remove pillows, blankets and sheets that could cover the baby's face, head or neck if there is any chance of falling asleep.

The one thing that does go in

The safe-sleep guidance is almost entirely a list of things to take out. The single exception is the pacifier, which the AAP recommends offering at nap time and bedtime, with nothing attached to it. Safe to Sleep specifically says not to attach a pacifier to stuffed toys or blankets, which rules out the plush pacifier holders sold next to loveys. The conditions are covered in pacifiers at bedtime.

What changes after the first birthday

The AAP's recommendations, by HealthyChildren's own footnote, are written for babies up to 1 year of age, and Safe to Sleep's back-sleeping instruction runs to the same point. No federal product standard sets an age at which a blanket, pillow or soft toy becomes acceptable in a toddler's bed. That leaves the step after 12 months as a judgment rather than a rule, and it is one to make with a pediatrician, especially for a child born preterm or with a health condition that affects breathing or movement.

When parents do make that step, the reasoning behind the infant rule still points the same direction.

Small and thin before large and thick. A light blanket the toddler can lift off with one hand is a different object from a quilt or comforter. Thick, heavy and weighted items stay out.

A soft toy that passes the toy rules. A lovey or stuffed animal brought into a toddler bed is a toy, and the same small-parts, button-eye and seam checks apply to it as to any other plush. A toy with a ribbon, cord or long loop does not belong in a bed at any age.

A pillow is a separate question. Pillows sit on every agency's first-year list, and an adult-size pillow is the wrong size and firmness for a toddler. Whether and when to add a small one is worth asking at a well-child visit rather than settling from a package label.

The move out of the crib itself is driven by climbing, not by bedding, and the mattress keeps the same firmness rule after it moves, which is covered in when to move a toddler from a crib to a bed. The cribs and bassinets that meet the federal sleep-product standards are compared in the best cribs and bassinets.

Common versions of the same mistake

The blanket tucked in at the foot. Safe to Sleep lists tucked-in blankets among unsafe items by name. A tuck that holds at bedtime does not hold against a baby who kicks and rolls overnight.

The small lovey because it is small. Safe to Sleep's phrase is "even if lightweight, small". Size is not the test. A cloth small enough to fit in a hand is large enough to cover a nose and mouth.

Bedding sold as a set. Older crib bedding sets, including many passed on secondhand, come with a quilt, bumper or pillow. The fitted sheet is the only piece that goes on the mattress for sleep.

Products that look like sleep gear. Loungers, nursing pillows and padded nests are sold in the same aisle as crib sheets. HealthyChildren's instruction is not to use products for sleep that are not specifically marketed for infant sleep, and the federal nursing pillow rule now prints that on the box.

Questions people actually ask

When can a baby sleep with a blanket?

The AAP, CPSC, NIH Safe to Sleep and CDC all advise no loose blankets in the sleep space for the first year. HealthyChildren.org says its safe-sleep recommendations apply to babies up to 1 year of age. For warmth, use a wearable blanket or one extra layer of clothing instead.

Is a small lovey safe in the crib?

Not for a baby under 1. Safe to Sleep lists loveys by name among the items to keep out of the sleep area, even if lightweight, small or tucked in. A lovey is fine for awake, supervised time outside the crib.

My baby can roll and lift their head. Can I add a blanket now?

The guidance does not change at rolling. A 2014 Pediatrics study of 8,207 sleep-related infant deaths found that rolling into objects in the sleep area was the predominant risk factor for infants aged 4 months to 1 year, and that older infants were more likely than newborns to have died with a blanket or stuffed toy present.

When can a toddler use a pillow?

Pillows are on every agency's list of items to keep out of a baby's sleep space in the first year. No federal standard sets an age for a toddler pillow, so ask your pediatrician at a well-child visit, and avoid adult-size pillows.

Can I tuck a blanket in at the foot of the crib?

No. NIH Safe to Sleep now lists tucked-in blankets among unsafe items in a baby's sleep area. A wearable blanket keeps the baby warm without a loose layer that can move over the face.
