A baby may stiffen up due to the startle reflex, which is a normal and involuntary reaction to sudden stimuli. It can also occur in certain medical conditions such as seizures or muscle spasms.
What causes a baby to stiffen up?
A baby may stiffen up due to various reasons, including the startle reflex, medical conditions such as seizures or muscle spasms. Let’s dive into more detail and explore this topic further.
-
Startle Reflex: One common reason for a baby to stiffen up is the startle reflex, which is an involuntary response to sudden stimuli. This reflex is often observed in newborns and infants up to around 4 months of age. As noted by the American Academy of Pediatrics, the startle reflex is part of the normal development process and helps babies learn to respond to their environment.
-
Seizures: In some cases, stiffening in infants can be associated with seizures. Seizures occur when there is abnormal electrical activity in the brain. According to the Epilepsy Foundation, seizures can manifest in various ways, including stiffening of the limbs. It’s important to note that if you suspect a baby is experiencing seizures, it is crucial to seek medical attention.
-
Muscle Spasms: Muscle spasms, also known as muscle rigidity or hypertonia, can cause a baby to stiffen up. This increased muscle tone can occur due to a variety of medical conditions, such as cerebral palsy or certain genetic disorders. If you notice persistent or concerning muscle stiffness in your baby, consulting with a healthcare professional is recommended for proper evaluation and diagnosis.

Reflexes in Babies: Reflexes play a significant role in a baby’s development and can often be observed during the first few months of life. These reflexes, including the startle reflex, help babies adapt to their environment and develop motor skills. Understanding these reflexes can provide insights into a baby’s physical and neurological development.
To add an interesting quote related to babies and reflexes, here’s a quote by renowned pediatrician Dr. Benjamin Spock: “Babies are smarter than we think. They choose their earliest caregivers based on their competence to fulfill their instinctual needs.”
Now, let’s visualize the information mentioned above in a table format:
| Causes of Baby Stiffening | Examples |
|---|---|
| Startle Reflex | Sudden loud noises, bright lights, or quick movements can trigger the startle reflex and cause the baby to stiffen momentarily. |
| Seizures | Abnormal electrical activity in the brain can lead to seizures, often characterized by muscle stiffening or jerking movements. |
| Muscle Spasms | Certain medical conditions like cerebral palsy or genetic disorders can cause increased muscle tone and rigidity in babies. |
Remember, if you have concerns or notice persistent stiffness in your baby, it is always best to consult with a healthcare professional for an accurate diagnosis and appropriate care.
See a video about the subject.
In this video on baby development, the instructor demonstrates a hold specifically designed for babies with stiff legs. The suggested technique involves holding the baby facing away from you, placing your arm under one armpit, and holding their opposite leg under the knee to bend the hip. This position can aid in improving hip and knee mobility for babies with stiffness in their legs. It is recommended to repeat the hold on both sides if needed.

Hypertonia is a condition that makes a baby’s muscles stiff and hard to move. It happens because of damage to areas of the brain and spinal cord that control muscle movements. While babies need to contract their muscles to move their bodies and sit upright, muscles that are continually contracted are less flexible.
If your child is healthy and has had no developmental problems so far, you likely have nothing to worry about. Children sometimes stiffen up when they’re having a bowel movement, especially if the stool is hard. Another theory is that your child is simply stiffening because he’s excited or frustrated.
Another theory is that your child is simply stiffening because he’s excited or frustrated. He may also be discovering new ways to use his muscles. Some babies stiffen up when they’re doing something they’d rather not, such as getting a diaper change or being put into their snow suit.
The Four Reasons Why Your Baby is Stiff Could Be:
- Hypertonia Hypertonia means your baby has an abnormally high muscle tone.
- Cerebral Palsy Cerebral palsy is the most common reason why your baby feels so stiff.

What does stiffness in babies mean?
Hypertonia is an umbrella term that describes when there is an abnormally high muscle tone in the infant’s body. High muscle tone causes the baby to be stiff and rigid, especially when held. Newborn babies with this condition may have difficulty with mobility and flexing.
Also, Why does my baby stiffen up and grunt? When your baby grunts, it usually means they’re learning how to have a bowel movement. They haven’t yet figured out how to relax the pelvic floor while also using abdominal pressure to move stool and gas through their system.
Herein, What are 3 early signs of cerebral palsy? Response to this: Possible signs in a child include:
- delays in reaching development milestones – for example, not sitting by 8 months or not walking by 18 months.
- seeming too stiff or too floppy (hypotonia)
- weak arms or legs.
- fidgety, jerky or clumsy movements.
- random, uncontrolled movements.
- muscle spasms.
- shaking hands (tremors)
Why does my baby straighten his body? Response: Startle reflex
It might also happen if they feel like they’re falling or if they’re moved suddenly. Startling may make a baby suddenly straighten their legs forward and throw back their arms. Their head may also jerk backwards, making their back arch.
Consequently, Why does my Baby stiffen up? Response will be: Some older babies stiffen up to resist doing something they dislike, such as getting a diaper change or being put into their car seat. All of these situations are perfectly normal. But in other cases, a baby stiffening their body or arms and legs can indicate a problem. What is hypertonia?
One may also ask, Why does my Baby nod a lot? The reply will be: Head nodding. Spasms that are due to an abnormality in your baby’s brain often affect one side of their body more than the other or may result in pulling of their head or eyes to one side. Infantile spasms are most common just after your baby wakes up and rarely happen while they’re sleeping.
What causes a baby to startle? As an answer to this: It’s very common for newborns and infants to startle. They fling their arms and legs wide, then bring them together. In most cases, this is a normal reflex known as the startle, or Moro, reflex. However, in rare cases, these movements may be a sign of a serious condition called infantile spasms.
Does colic make a baby stiff? The answer is: Often this type of stiffening is no big deal. Children might also stiffen up their bottoms when they’re having a bowel movement, especially if the stool is hard. And colic can make babies pull in and tighten their arms and legs, tense their abdomen, and clench their fists.
