Momma’s:
This concept I’ve recently been getting training on.
Here is a colleague’s great explanation for swaddling and why it may not be what’s needed for baby.
A new concept for many of us.
✨ Swaddling ✨
Most new parents think that they need to swaddle their baby. But the truth is that swaddling can hinder a baby’s development.
Babys are born with hundreds of primitive reflexes. These reflexes are how a baby learns to nurse, close their hand around your finger, and eventually roll over and crawl.
One of these reflexes is the Moro or startle reflex. This reflex is why a baby may wake up when they are put down. They feel the change of position and “startle” awake. This reflex is present at birth and should go away by 3 months. It integrates into the brain as the brain grows and becomes more developed. Simply put, a baby had to use this reflex over and over until the brain is developed enough to not respond to it.
Parents swaddle babies to reduce their startle reflex so that they both get better sleep. The issue is, by reducing the reflex, the brain development is affected.
Babies who are swaddled don’t get to “practice” their startle reflex and therefore their brain won’t make the connections needed to turn the reflex off by 2-4 months when it should naturally disappear.
In our office, we often see babies around 4-6 months who struggle to sleep. Mom is exhausted and considering sleep training but knows there’s something else going on. Swaddling for too long + the 4 month sleep progression are a bad combination and can cause the whole family to become stressed and exhausted.
Typically, these parents swaddle their baby so that baby can sleep longer periods. Then when they stop swaddling because baby can roll, their baby still startles and wakes up easily. They turn to the weighted sleep sacks which just prolong and worsen this issue. Now the startle reflex gets stronger and persistent. Brain development has been altered and the milestones of integration of all primitive reflexes are affected which in turn affect when a baby learns to roll, sit, crawl, and walk.
This is why we DO NOT recommend swaddling. It has neurological consequences for a baby’s development.
Swaddling does mimic how a baby felt in the womb. So IF you decide you need to swaddle your newborn baby, only do so for two weeks maximum!
