Quick answer

Choose baby pajamas made from organic cotton that fit snugly (not tightly) and are free of loose strings, buttons, or hoods. For cold nights, use footed pajamas or a wearable blanket instead of adding loose bedding.

Why fabric matters for safe sleep

Organic cotton is breathable and reduces the risk of overheating, a known SIDS risk factor. Unlike synthetic blends, it wicks moisture without trapping heat. Look for GOTS-certified options to ensure no harsh chemicals touch your baby's skin.

Finn + Emma pajamas are made from 100% organic cotton with non-toxic, eco-friendly dyes, so you can trust the fabric next to your baby's skin.

Snug fit vs. tight fit: know the difference

Safe sleep guidelines require pajamas to fit snugly—close to the body without being restrictive. A snug fit prevents fabric from riding up over the face. Avoid anything labeled 'loose fit' or with extra fabric in the torso.

Check the waistband: a wide elastic band (like the one on Finn + Emma's pajamas) provides comfort without digging in, and helps keep the pajamas in place during movement.

Step-by-step guide to choosing safe baby pajamas

  1. 1. Check the fabric: Choose 100% organic cotton. It's breathable, hypoallergenic, and free from flame-retardant chemicals often found in synthetic sleepwear. Avoid polyester or blends that can cause sweating and overheating.
  2. 2. Ensure a snug (not tight) fit: The pajamas should follow the body's shape without excess fabric. Check that the arm and leg openings are close-fitting but not restrictive. Use the 'two-finger test': you should be able to slide two fingers between the fabric and your baby's skin. Loose pajamas can ride up over the face—a suffocation hazard.
  3. 3. Choose footed or non-footed based on room temperature: Footed pajamas keep feet warm without socks, which can fall off. For warmer rooms, non-footed with separate socks is fine. If using a sleep sack, you can skip footed pajamas. Never use both footed pajamas and a sleep sack—your baby could overheat.
  4. 4. Avoid loose parts and decorations: Skip pajamas with buttons, snaps that can come undone, ribbons, or hoods. These are choking or entanglement hazards. Choose one-piece zip or snap closures instead. If the pajama has a hood, remove it or choose another style.
  5. 5. Layer wisely for cold weather: In winter, use footed organic cotton pajamas under a wearable blanket (sleep sack) with a tog rating appropriate for the room temperature. Do not add loose blankets. Check your baby's neck or chest for warmth—if it feels sweaty, remove a layer.
