Focus on sitting

Typically developing infants reach the important sitting milestone at 6-8 months. They have good balance in sitting, are able to reach in all directions and start to move from sitting into the crawling position. 

Preterm infants tend to sit a little later, at 8-10 months, even when the corrected age is used. 

Infants with coordination difficulties (DCD), those at risk for autism, and infants with global developmental delay, joint hypermobility, low muscle tone and a very cautious nature are often late learning to sit. 

Learning to sit independently is a very important milestone: the infant gains a whole new way of seeing the world and the hands are freed up for exploring objects and using gestures to communicate.

  • Chart your infants progress over the stepping stones to the major milestone of sitting with good balance and the ability to reach in all directions. 

    The chart provides age ranges for typical development, and makes allowance for infants born preterm and those with low muscle tone and joint hypermobility. 

    Infants born prematurely, and those with joint hypermobility/low muscle tone often only sit a month or two later than typically developing infants. 

  • How infants learn to sit with good balance, difficulties experienced by infants with joint hypermobility, low muscle tone, preterm birth, autism and coordination difficulties. 

  • Brain development is promoted when infants and toddlers engage in intentional, goal directed actions: they know what they want and use all their available resources to achieve their goal. 

  • Infants and toddlers born preterm, and those with low muscle tone, joint hypermobility and delayed motor milestones, often have tightness in some muscles that affects their posture, balance and coordination.
