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.
