Babies are cute, aren't they? From their chubby cheeks to their tiny hands that double as weapons when it comes to pulling our hair and pinching our noses. Speaking about their hands, have you ever wondered why babies close them in a tight fist? Is it because of instinct or something else entirely? In this article, we will be diving into the world of newborns' hand movements and figuring out what's really going on.
What is Infant Hand Grasp?
Before we get started with everything else, let's take a moment to understand the concept of 'infant hand grasp'. The term refers to how a baby holds onto objects using its fingers or palms. This behavior is deemed essential for an infant because it helps them interact with the world around them while also aiding in improving muscle strength and coordination.
That being said, there are two types of infant grasps - palmar grasp and pincer grasp. Palmar grasp involves little ones holding things within their palm whereas pincer grip has infants picking up objects using only their index finger and thumb.
Now that we've got those definitions out of the way let's dive into why exactly babies clench their fists so tightly!
First Two Months
The first few months after birth can be frustrating for new parents who simply cannot figure out how to stop everything from making your bundle of joy cry every time! When it comes specifically to newborns closing fists during these months, though few reasons stand at play:
-
Reflexes That Are Present At Birth: Infants tend to come equipped with several reflexes - one amongst which includes throwing arms fully stretched followed by pulling back towards themselves immediately (Moro Reflex) sometimes causing an irrepressible jerk movement where they end up squeezing fingers together (aka Asymmetrical Tonic Neck Reflex).
-
Keeping Themselves Warm: Newborn babies have terrible control over their body temperature, so naturally, they try to snuggle up into a ball and maintain as much warmth as possible. Babies closing fists is an open exhibition of this behavior of cuddling one's fingers.
-
The Startle Response: As mentioned above in the first point where Moro reflex exhibits stimuli responses where newborn reacts purely based on sensation which later results in subtle muscular movements including hand-related manifestations such as clenching their hands tightly.
3-6 Months
As babies grow older, they develop better motor skills over time. Consequently, during months three through six after birth you should see that your baby begins to let loose with their grip while also learning how to pick items up more proficiently using its fingers; thumbs mostly.
Even though there isn't a definitive reason why little ones tend to keep clenching tight at the start of infancy - it tends to slacken by third-month allowing them broader perspective and freedoms in indulging with engaged objects around them yet clinging towards comfortable spaces "they are still growing trust issues."
Infants may still close fists because:
- Lack Of Coordination: Even when infants reach between 4–5 months nursing milestones “Hand-to-mouth” pattern establish growth making for unavoidable fumbles and clangs but once they catch things—transferring those from palm-to-palm (palmar grasp) or bear paw-like grips shifts focus significantly rather than just squeezing harder (
there goes the sippy cup! Oh no! Thanks grubby hands!).
Beyond Six Months
After six months post-birth babies will begin utilizing both palmar grasps as well pincer grips early signs indicating development hand-eye coordination which makes exploring new materials digestible not solely foodstuffs other variants too (nope that's chalky ! Nom Nom Nom.)
At this stage, parents can be relieved that their babies have started unclenching the fists they used to keep as hostilities. At six months or after, baby's hand closing situation of staying shut may become suspicious again but only for a reasonable cause this time - like being sleepy (when the five senses switch off Grasping is left intact !).
While infants' muscles grow and develop over time, there is no doubt they will continue exploring new ways of using them. Who knows? Maybe someday we'll discover some secret society within these tight fists.
Babies clenching their hands can certainly be an overwhelming experience for parents who are already struggling with taking care of lil munchkins. But through understanding those natural reflexes passed on by evolution means simple actions capture infant’s movement tendencies which might’ve not been apparent before! And once you grasp why it happens, it becomes another charming attribute unique in its own way among many adorable quirks possessed by newborns.(cough) obsession with ceiling fans(cough!)`.
