As a child grows, they learn and acquire more refined gross and fine motor skills, as well as developing social and emotional skills. As the child matures, primitive reflexes that are initially developed to aid survival, become integrated into more refined movements. Children tend to acquire these skills in an orderly fashion and within certain age brackets. This pattern of skill acquisition, often referred to as "Typical Development", is used to monitor a child's developmental progress. In some cases late acquisition of these 'milestones' can indicate developmental delay. However, it must be remembered that the time span within which acquisition of these skills are still considered 'typical', are wide [1], and that some children may skip a milestone altogether.

The early you start the better it is as the first three years of any child are critical for brain development. You need to act fast if you feel there’s an abnormality in your kid. Consult a good pediatrics doctor to clear your doubts.
