When the child starts to sit: we disassemble the features of the development of the skill
In the first six months of life, the baby learns a lot of new skills: he holds his head well, overturns, actively creeps. The most mobile kids try to lift the body, grabbing the back of the crib or Mom’s hands. Consider when a child begins to sit alone, and what to do if this does not happen within the time frame set by pediatricians.
The development of the musculoskeletal system of a newborn occurs in several stages. The backbone, which initially represents an absolutely straight line, gradually acquires natural curves. Approximately 3-4 months, when the baby begins to hold the head well in the supine position, cervical lordosis is formed – the upper vertebrae is bent forward. By the half-year as a result of high motor activity and attempts to transfer the upper body to a vertical position, the middle part of the chest under the action of gravity slightly bends back. At this stage of development, the spine is able to withstand increasing loads and is ready to start sitting down. In accordance with the average pediatric standards, the child must:
- in 6 months to sit down with support;
- in 7 months for a while to sit without support;
- in 8 months without the help of an adult sit down from a lying position or standing on all fours.
