Let’s Talk Swaddling: Safety, Reflexes & What Your Baby Really Needs. Swaddling is often one of the first soothing tools new parents try—but it also comes with a LOT of questions.
Does it help sleep? Is it safe? Is suppressing the startle reflex ok?
What is the Moro Reflex?
That sudden flailing movement your newborn makes when they’re startled or shifted quickly? That’s the Moro reflex—a totally normal, healthy reflex that helps babies adjust to the outside world. It peaks in the first couple of months and fades by around 4 months.
Why swaddle?
Swaddling gently reduces the intensity of the Moro reflex so your baby doesn’t startle awake every few minutes. It mimics the cozy containment of the womb and is thought to lead to longer stretches of sleep, help calm the nervous system and make an easier transitions between sleep cycles
Should we suppress the Moro reflex?
Not entirely. The reflex has a purpose—it supports neurological development and helps babies integrate sensory input. Over-suppressing it (especially with tight, arms-down swaddles) may: limit movement and motor skill development
Interfere with feeding cues (babies use their hands to show hunger) reduce self-soothing opportunities
Instead of "shutting it down," think of swaddling as a way to gently buffer the reflex while your baby matures.
Swaddling doesn’t work for every baby. And that’s okay. If your little one resists it or seems frustrated, try keeping their arms out or arms up swaddling, consider baby wearing or skin-to-skin during the day or creating a soothing bedtime rhythm without a swaddle.
Your baby’s cues will always tell you what’s working—and what’s not. Drop a comment or message if it worked for you and your baby.
