Developmental milestones essentially refer to the range of normal development of a child ageing from 0 years old to the age of 5. It’s important to know if a child’s physical, language, social and cognitive abilities are normal or if they show signs of developmental delay because the faster it is treated, the more significant will the improvement be. Take a look at this list and consult with your doctor if your child is not able to do some of the skills mentioned below.
