Have you ever noticed that your little one suddenly flinches, spreads his arms out to the sides, and then pulls himself back to his body? Or does this happen to you when you try to put your baby to bed? Many parents get a little worried when they see this. But don't worry, this is normal for most babies. Today we are going to talk about this so-called 'flinching behavior', which is the Moro Reflex .
What exactly is the Moro Reflex?
Simply put, the Moro Reflex is an automatic response that newborns have at birth. This means that if a baby feels like they are about to fall, or if they are suddenly startled by something, they will automatically react in this way. Isn't it amazing? It's like a built-in defense system.
Did you know that the Moro Reflex is said to help babies take their first breath after they are born? It was first described in 1918 by a German pediatrician named Ernst Moro. So it is called the Moro Reflex after him.
Why is the little one shaking like this? What exactly is happening then?
You've probably felt this too, especially when you're putting your baby to sleep. Here are some of the things your baby does:
- Suddenly , both hands are spread out to the sides , maybe even a little upwards.
- Spread your fingers wide and bend your thumbs a little.
- It's like throwing your head back .
- Sometimes I even start crying .
All this happens in a few seconds. Then the baby brings his arms back to his body, bends his elbows, and calms down. Just imagine, even the slightest noise can sometimes cause this.
Why do doctors look at this? What do they learn from it?
During standard tests that doctors do after a baby is born, the Moro reflex is definitely checked. The reason for this is that it gives a good idea of how the baby's nervous system is functioning . That is, it is a good measure of whether the baby's brain, spinal cord, and nerves are working properly.
Not only that, but sometimes this reflex is tested to find out if there are any problems with the baby's nervous system, or to rule out any medical conditions.
Can you check the Moro reflex at home? How do you do it?
Yes, you can also very carefully check your baby for the Moro Reflex. But this is something that needs to be done very carefully . One way is to hold your baby in your hands (with good support for the head) and suddenly lower it a little. This will make the baby feel like it is going to fall, but there is nothing to worry about because you are still holding the baby and the baby's head well. Never let the baby actually fall.
A baby with a normal Moro reflex will have a slightly startled look on their face when you do this. They will spread their arms out to the sides, turn their palms up, and curl their thumbs. They may even cry a little. When you give your baby good support for their head again, they will pull their arms back to their body, bend their elbows, and calm down.
Remember, this is done very gently and carefully. You don't want to scare the baby or cause any harm. If in doubt, it's best to ask your pediatrician.
Why do babies have this Moro reflex?
This is actually a safety mechanism that babies have. Imagine, if a little baby feels like they're about to fall, they can't scream, "Please save me!" or ask for help. That's why this reflex kicks in automatically, as if trying to get attention.
The Moro reflex occurs when the vestibular system in the baby's inner ear, which controls balance, detects the sensation of falling. It then sends emergency signals to the baby's brainstem . That's when this reflex is activated.
Even as a fetus, this reflex can occur as early as the second trimester of pregnancy. However, it usually becomes more noticeable in the third trimester. In most cases, the Moro reflex disappears by the time the baby is about 6 months old .
What usually happens is that this Moro reflex gradually changes to another startle response, the Strauss reflex . This Strauss reflex is present throughout our lives. You've probably noticed that if we suddenly hear a loud noise, we startle and go to see what happened. That's it.
Are the Moro Reflex and the Startle Reflex two different things? Or one?
The answer is yes or no. There is more than one type of startle reflex. The Moro reflex is the one that newborn babies have. But by the time they are about 6 months old, it should change to the Strauss reflex.
What diseases does a doctor look for with this reflex?
Pediatricians use the Moro reflex to check whether a baby's nervous system is working properly. They also use it to diagnose and rule out conditions such as:
- Birth injuries (for example, damage to a nerve in the arm)
- Some congenital muscle diseases (congenital myopathy)
- Infantile spasms
When a doctor tests this reflex, they focus on several key things:
1. Strength of the reflex: Sometimes, this may be a little weak in premature babies, which is normal. However, if there is something affecting the baby's central nervous system , that can also be indicated by a weak reflex.
2. Symmetry of the reflex: The Moro reflex should be equally effective on both sides (left and right). This means that both arms should be extended equally. Otherwise, if the response is weak on only one side, it may indicate an injury (e.g., a broken collarbone) or a neurological disorder.
3. How the reflex is related to the baby's age: In premature babies, this reflex is initially weak, but gradually becomes stronger. However, by about 6 months, it should have completely changed to the Strauss reflex. If it has not changed, it can be a sign of developmental delays or other problems.
What happens if your baby still has the Moro reflex at 6 months?
If you think your baby still has the Moro reflex after 6 months, be sure to talk to your pediatrician about it. It could be a sign that your baby's nervous system is working differently than expected. Babies who still have the Moro reflex after 6 months may:
- Being overly sensitive to sudden sounds and events.
- Shows a slightly anxious nature.
- Maybe even hyperactive .
But don't worry. If your baby has this condition, there are treatments that can help. These involve training your baby's nervous system to respond properly through specific exercises. Your doctor can tell you more about this and make appropriate recommendations.
Even though it's sad when the little one cries and cries, this is important!
It may not be the most pleasant thing to watch your little one startle and cry out in fear, thinking they're going to fall. But, moms and dads, remember, the Moro reflex is a normal, healthy thing . And it's a key way for doctors to make sure your baby is okay.
So, if you have any questions or concerns about your baby's Moro reflex, be sure to talk to your baby's doctor. He or she can explain this reflex to you, how it works, and whether it's anything to worry about.
Finally, things to remember (Take-Home Message)
- The Moro Reflex is a normal, automatic response in newborn babies. It is designed to protect them.
- This is noticeable when the baby feels like they're about to fall, or suddenly jumps. They'll flail their arms, and maybe cry.
- This is a good sign that the baby's nervous system is healthy .
- This reflex usually disappears by about 6 months of age .
- If this is still present after 6 months, or if there is a problem with the strength or symmetry of the reflex, definitely see a pediatrician.
- This is normal for babies, so don't worry unnecessarily . However, it's best to talk to a doctor if you have any concerns.
It's great that you care about every little thing about your little one. It's also very important to be aware of things like this.
