Is it normal for a 6-month-old baby not to sit steadily?

It is usually normal for a 6-month-old baby to be unable to sit steadily, and there is generally no need for excessive concern.

At 6 months of age, babies typically have relatively weak muscle strength and poor spinal support. They often need to extend their hands forward and use their arms to support themselves when sitting up. It is common for them to be unsteady when first learning to sit. Moreover, each baby develops at a different pace. Babies who are heavier or taller may experience delayed sitting due to the challenges their body size poses to coordination and motor control. Additionally, premature infants often develop more slowly overall, including in motor skills, which may also result in instability when attempting to sit at 6 months.

Parents can help by introducing calcium-rich complementary foods into the baby’s diet to increase calcium levels, supporting bone development and improving stability when sitting.
