Is My Newborn ROLLING? Learn about Newborn Curl / Scrunch

What Is the Newborn Curl?

Newborns display many fascinating behaviors, one of which is the "newborn scrunch" or "newborn curl." This behavior, where babies pull their legs toward their torso or roll slightly to their side while lying on their backs, is completely natural. It mimics the fetal position they held in the womb and is rooted in physiological development. After birth, this familiar position helps babies feel secure. 

Rest assured, it’s harmless and temporary.

 

Why Does It Happen?

The Curl is linked to a developmental state called **physiological flexion**, where a baby’s muscles remain naturally flexed after birth. This muscle tone develops during pregnancy and results in the signature fetal curl. Even after birth, babies instinctively revert to this posture, which may cause slight side rolling. This behavior is more common in full-term babies, as preemies often lack the same muscle tone. Over time, as muscle control improves, the curl becomes less noticeable.

Is It Safe?

While the newborn scrunch might cause slight side rolling, it is generally safe as long as you follow **safe sleep guidelines**. The American Academy of Pediatrics (AAP) recommends always placing babies on their backs to sleep. If your baby starts on their back but ends up slightly on their side due to the scrunch, that’s okay as long as their sleep environment is secure.

 

Tips for Safe Sleep with the Newborn Curl

Here are some ways to keep your baby safe while accommodating this natural behavior:

1. Adjust Swaddling Technique with The Ollie® Swaddle 

Position your baby’s arms gently down by their sides instead of leaving them across their chest or one arm out. This stabilizes their posture from that slight curl.

2. Avoid Sleep Positioners

Products like wedges or bolsters may seem helpful, but they can increase the risk of suffocation or entrapment. Both the U.S. Consumer Product Safety Commission (CPSC) and the Food and Drug Administration (FDA) warn against their use.

3. Maintain a Clear Sleep Space

Use a firm mattress with a tight-fitting sheet and avoid pillows, blankets, or toys in the crib. A bare crib is the safest environment.

4. Always Start on Their Back

Always place your baby on their back for sleep. If they roll slightly due to the scrunch, it’s usually fine as long as the crib is safe and free of hazards.

 

When Does it Go Away?

The newborn Curl typically fades within the first two months as babies develop more control over their muscles. By around four months, most babies can roll from their stomach to their back, and by six months, they may roll from back to front. These developmental milestones indicate growing strength and coordination, reducing the prevalence of the scrunched posture.

 

Supporting Your Baby’s Development

To help your baby grow out of the newborn curl:

Encourage Tummy Time: Tummy time strengthens neck, shoulder, and arm muscles, preparing your baby for rolling and other motor milestones.
Practice Gentle Play: Activities like gentle stretches or letting your baby kick freely can also improve muscle tone.

The newborn curl is a natural and temporary behavior that reflects your baby’s transition from the womb to the outside world. By understanding this behavior and following safe sleep practices, you can support your baby’s comfort and safety. Remember, every baby is unique, and consulting your pediatrician can provide personalized guidance if you have concerns.

Enjoy these precious moments—they pass quickly, and your little ne is growing and learning every day!
