My baby's arms and legs are usually tight and stiff. Does this muscle tightness negatively affect sitting and walking development?

Babies having tight arms and legs is generally a normal developmental stage. In newborns and early months, extensor muscle tone (tightening muscles that straighten) is more dominant; this is why arms and legs often appear tight and sometimes fists are clenched. This decreases over time (usually around 4-6 months) and becomes more fluid movement.
Tightness in arms and legs alone doesn't negatively affect sitting or walking; in fact, muscle tone provides the foundation for motor development. Consulting your pediatrician is important in these situations:
- If there's significant resistance when you try to move your baby's joints passively, and you can't move them,
- If tightness is only on one side of the body (left-right difference),
- If after 6 months the tightness doesn't decrease, in fact gets worse,
- If there's noticeable delay in head control, rolling, sitting, and other milestones.
Generally, if your baby is meeting other developmental milestones for their age (smiling, reaching for objects, holding their head up, etc.), don't worry. But getting a check-up within 2-4 weeks would be beneficial.
