By the age of 6-8 months typically developing babies are able to sit independently, reach in all directions, pick up and move toys with one or both hands. It is important to remember that their everyday life has provided many and varied opportunities for practicing sitting.
How infants learn to sit with good balance, difficulties experienced by infants with joint hypermobility, low muscle tone, preterm birth, autism and coordination difficulties.
I often see infants aged between 11-15 months who have learned to sit but are not rolling, hate being on the tummy and are not crawling. Parents are understandably getting anxious about their infants development and may have been advised to work on tummy time.
