Normal newborn movement is characterized by a combination of reflexive actions, uncoordinated movements, and developing motor skills.
Here's a breakdown of what to expect:
-
Reflexive Movements: Newborns are born with several reflexes, such as the Moro (startle) reflex, grasping reflex, sucking reflex, and rooting reflex. These are involuntary responses to stimuli and are essential for survival.
-
Uncoordinated Movements: Their movements often appear jerky, uncoordinated, and random. This is because their nervous system is still developing and learning to control their muscles.
-
Head Control: A newborn's head will sag when lifted and needs to be supported. They can turn their head from side to side when lying on their stomach.
-
Eye Movements: Eye movements are frequently uncoordinated, and they may appear cross-eyed at times. This generally improves as their eye muscles strengthen.
-
Limb Movements: Expect random arm and leg movements. They may kick and flail their arms, but these movements are not yet controlled.
-
Muscle Tone: Newborns typically have flexed arms and legs.
Examples of Normal Newborn Movements:
- Startling in response to a loud noise (Moro reflex).
- Grasping a finger placed in their palm (grasping reflex).
- Turning their head towards a touch on their cheek (rooting reflex).
- Sucking on a nipple or finger (sucking reflex).
- Jerky arm and leg movements.
When to be Concerned:
While most newborn movements are normal, consult a pediatrician if you observe the following:
- Stiffness or rigidity in limbs.
- Constant floppiness (very low muscle tone).
- Seizure-like activity.
- Unequal movement of the arms and legs.
- Lack of reflexes.
In summary, normal newborn movement is a blend of reflexes and uncoordinated actions, reflecting their developing nervous system and muscles. Supporting the head, random limb movement, and uncoordinated eye movements are typical characteristics.
