Short answer: A noticeable, consistent difference in how easily a child can control each hand — one holding a pencil comfortably, the other gripping tightly, awkwardly, or tiring quickly — can reflect a subtle difference in muscle tone or motor control between the two sides of the body. It is not always obvious until school tasks like handwriting demand fine, sustained hand control.

Everyday tasks like holding a cup, stacking blocks or pointing rarely demand much from each hand individually — a mild difference between the two sides of the body can go unnoticed for years. Handwriting changes that: it needs one hand to hold a pencil with fine, sustained control for long stretches, which can bring a subtle asymmetry in muscle tone or motor control into clear view for the first time once formal schooling begins.
Occasionally switching grip or complaining of a tired hand is common in early writers. It's worth paying closer attention when one hand consistently holds a pencil comfortably while the other grips it much more tightly, stiffly, or awkwardly — every time, not just occasionally — especially if that same hand is also a little clumsier with buttons, zips or other fine tasks. Parents in Rishabh Vihar and Karkardooma have raised this exact pattern after their child started school writing tasks. A consistent one-sided difference like this is worth discussing with a cerebral palsy rehab in Delhi team, since tone-related differences are sometimes picked up later in childhood, not only in infancy.
If this one-sided pattern is new, mild and doesn't affect anything beyond handwriting comfort, simple strategies like a pencil grip aid and shorter writing bursts can help in the meantime. If it is consistent, affects more than just writing, or comes with any other one-sided weakness or stiffness, a motor assessment that looks at tone and control on both sides of the body is worth getting, rather than assuming it will even out with more handwriting practice.

No. Hand fatigue during early handwriting is common and often just reflects a developing skill. It's the consistent one-sided difference in grip, tightness or control -- not simple tiredness -- that is worth paying attention to.
Many everyday tasks don't demand much sustained, fine control from each hand individually. Handwriting does, so it can be the first activity that reveals a subtle difference between the two sides.
Not necessarily -- there can be other reasons for a one-sided grip difference. A proper assessment is the only reliable way to understand the cause rather than guessing from this sign alone.
It typically looks at muscle tone, strength and coordination on both sides of the body together, not just the hand used for writing.
