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 joint hypermobility, low muscle tone and a very cautious nature are often late learning to sit. 

They also tend to be less active in sitting, and miss out on the reaching, twisting, ans shifting about that active typically infants engage in.

  • 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. 

  • Some infants skip the crawling stage altogether, and instead scoot around, often at great speed, on their buttocks. 

    The infant may sit with one leg bent forwards, foot on the floor and push on the opposite arm. Infants who move like this always sit with the same foot in front. 


  • Importance of attention and emotion regulation for optimal brain development

    Infants acquire new abilities and skills through active experience; they learn by doing. 

  • 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.

    Tightness in the hip abductor muscles

    The hip abductor muscles pass over the side of the hips. The iliotibial band extends from the lower back over the side of the hip and knee joints. 

    Tightness of the hip abductor muscles is common in infants who lie and sit with the legs wide apart and the hips twisted outwards.
