The Essential Guide to Baby Sweater Safety (AAP Rules)

Oct 24, 2025 By SwaddleAn

When it comes to baby sweater safety, style is secondary — what truly matters is protecting your little one. This guide helps you choose and use sweaters with confidence. It is based on advice from pediatric experts. This guide will cover four essential safety principles.


Key Takeaways

  1. Avoid overheating: Always dress your baby in one more light layer than what you are wearing. Overheating is one of the main risk factors for SIDS (Sudden Infant Death Syndrome).
  2. Remove strangulation hazards: Cut off all drawstrings on hoods, collars, or waistbands. According to safety regulations, children’s clothing should not have drawstrings around the head or neck area.
  3. Check for choking risks: Gently pull on all buttons, decorative beads, and small accessories to make sure they are securely attached. If anything feels loose, remove or sew it back on immediately.
  4. Never let your baby sleep in a sweater: Sweaters are soft and loose items in a crib, which can increase the risk of suffocation. Instead, use a wearable blanket to keep your baby warm safely.

What Are the 3 Leading Causes of Infant Death Every Parent Should Know

  1. Overheating & SIDS: Putting too many layers on your baby at bedtime can significantly increase the risk of SIDS. Always check the back of your baby’s neck. If it feels warm and dry, that’s perfect; if it’s sweaty, your baby is too hot.
  2. Strangulation: Drawstrings on hoods, collars, or any cords around the neck can get caught on objects and cause serious strangulation hazards. ALWAYS CUT THEM OFF.
  3. Choking: Buttons, beads, or small decorative pieces can come loose and become choking hazards if your baby puts them in their mouth. Always check that these parts are securely attached before dressing your baby.

Why is Overheating a Major Risk Factor for SIDS?

According to AAP guidelines baby clothing, overheating is one of the preventable risk factors linked to SIDS. AAP recommends dressing babies in light, breathable layers and making sure they never get too hot, especially while sleeping.

What Does the AAP Really Say About Dressing Your Baby for Sleep?

The AAP’s golden rule is simple: “Dress your baby in one more light layer than you’re wearing.” For example, if you feel comfortable in a long-sleeve shirt, dress your baby in a bodysuit and a thin sweater.

This rule helps keep your baby warm enough without the risk of overheating.

Is My Baby Too Warm? How to Really Tell if They Are Overheating

The best way to check your baby’s temperature is by feeling the back of their neck or their chest. If it feels warm and dry, your baby is comfortable. If it feels hot or sweaty, your baby is too warm and needs to have a layer removed. Don’t rely on their hands or feet, they naturally tend to feel cooler.

Is It Safe for My Baby to Sleep in a Sweater?

Are sweaters safe for babies to sleep in? No, according to safe sleep guidelines, babies should not sleep in sweaters while in a crib or bassinet. Sweaters are soft, loose items that can accidentally cover a baby’s face or cause overheating. 

Both of which increase safety risks. To keep your little one warm and secure, choose a wearable blanket or properly layered sleepwear instead.


What Are the Biggest Physical Dangers in Your Home (And How Do You Fix Them Now)?

Overheating is not the only risk with baby clothes. Baby clothing safety guidelines highlight the importance of addressing physical hazards that can cause preventable accidents. 

There are two very serious dangers with baby clothes:

  1. Strangulation from drawstrings.
  2. Choking from small parts that break off.

Because of these dangers, both are strictly regulated. The regulator is the U.S. Consumer Product Safety Commission (CPSC).

Are Drawstrings on Baby Sweater Really That Dangerous?

Drawstrings are a deadly hazard. This applies to any drawstrings on hoods or collars. They pose a serious risk of strangulation. Why? They can get caught on many items, including:

  1. Playground equipment
  2. Crib parts
  3. Other objects

CPSC safety regulations prohibit drawstrings around the head and neck area on children’s clothing. Always cut them off immediately.

How Can a Simple Button or Loose Thread Become a Deadly Choking Hazard?

When it comes to strangulation risk in baby clothing, small details matter. Buttons, beads, bows, or other decorative pieces can loosen and become choking hazards.

Buttons, beads, bows and other small decorative items can fall off and become a choking hazard.

If your baby puts them in their mouth. Always gently tug on these attachments before dressing your baby. Also, watch out for loose threads or yarn that could wrap around tiny fingers or toes and restrict circulation.


How Can You Be Sure Your Baby's Sweater Is Truly Safe and Chemical-Free?

Babies have extremely delicate and sensitive skin. Choosing non-toxic baby clothes is essential.  

It’s important to choose clothing made from non-toxic, breathable materials that are safety-certified, such as OEKO-TEX®. This helps prevent rashes, eczema, and other allergic reactions in babies.

What Do OEKO-TEX® and GOTS Really Mean? (And Why Do They Matter for Your Baby?)

The OEKO-TEX® Standard 100 certification is a safety guarantee. It means every part of the product is carefully tested. This includes the fabric, stitching, and even the buttons. This certification confirms the product is free from harmful chemicals that could irritate a baby’s skin.

That is why at SwaddleAn, all of our baby sweaters are OEKO-TEX® Standard 100 certified.

GOTS (Global Organic Textile Standard) goes even further: this certification verifies the organic origin of fibers (such as organic cotton). This ensures that the entire production process — from farming to dyeing — follows strict environmental and social standards.


Frequently Asked Questions (FAQ)

Do I need to wash new clothes before my baby wears them?

Yes, absolutely. Always wash new clothes. They may contain dust, bacteria, or chemicals from production and shipping that can irritate your baby’s sensitive skin.

Is it safe for a baby to wear a sweater in a car seat?

A thin, well-fitted sweater is safe. However, never dress your baby in bulky jackets or puffy sweaters under a car seat harness. Thick layers can create dangerous gaps that reduce the harness’s effectiveness in protecting your baby during a crash.
