Why Are Newborn Movements Different After Birth?
Your baby lived in a warm environment before birth, with little need to make any independent movement. After birth, the nervous system controls muscles, regulates temperature, and responds to sound, light, and touch.This adjustment takes time as your baby's brain and nerves are still immature. This can lead to uncoordinated movements, including shaking or trembling while awake.
What Do Newborn Shaking or Trembling Movements Look Like?
Small, rapid movements in the hands, arms, legs, or chin characterise trembling. They happen when your baby is awake, crying, feeding, or reacting to stimulation.The shaking is also brief and stops when your baby is comforted, fed, or held close. It does not involve loss of awareness or irregular eye movements.
Why Do Some Newborns Shake or Tremble While Awake?
The most common reason is an immature nervous system. Your baby's brain is still learning how to control muscles. Other reasons are mentioned below.- Response to cold
- Hunger or crying
- Overstimulation
- Normal muscle reflexes
How Does the Nervous System Affect Newborn Tremors?
Nerve connections in your baby's brain are still developing at birth. Signals between the brain and muscles may not travel properly, leading to brief shaking.As they mature over the first few months, muscle control improves, and tremors subside. This process is part of their neurological development.
When Are Newborn Tremors Considered Normal?
Normal newborn trembling:- Occurs when your baby is awake
- Stops when the baby is soothed
- Does not worsen over time
- Happens without changes in skin colour or breathing
Can Blood Sugar or Calcium Levels Play a Role?
Low blood sugar or low calcium levels may cause tremors in some babies. It is more common in babies born early or who had difficult births. Your baby may have tremors if you have diabetes.Hospitals regularly monitor high-risk infants to provide prompt treatment and resolve issues when detected early.
How Can You Tell the Difference Between Tremors and Seizures?
Tremors stop when you gently hold the affected limb. Seizures do not. So, pay attention to the following signs:- Movements that do not stop with touch
- Stiffening of the body
- Eye rolling or fixed staring
- Changes in breathing pattern or skin colour
- Repeated episodes without triggers
Which Babies Are More Likely to Have Tremors?
Newborn shaking is more commonly seen in the following situations:- Premature babies
- Babies with low birth weight
- Babies are exposed to stress during birth
- Babies are adjusting to temperature changes
How Do Doctors Evaluate Newborn Tremors?
They observe your baby's movements, alertness, feeding patterns, and reflexes. They may also check blood sugar or calcium levels if needed.Most babies do not require treatment; monitoring alone is sufficient unless additional symptoms are present.
What Can You Do to Comfort Your Baby?
