Overview about Developmental Milestones
The development of communication, gross motor, fine motor, problem solving, and personal social functioning is step-wise in children. The progressive development and the different skills the child develops are classified into milestones. For a child to be said is normally developing, he or she must achieve the suggested developmental milestones by the end of the given age.
Advice for Parents to Help Children Achieve Good Developmental Milestones
Communication can be improved by playing “I Spy” with the child or the use of parallel talk. Gross motor skills can be improved by taking the child to the playground, practicing climbing up the slide, sliding down, or playing “Simon Says”. Fine motor skills are improved by asking the child to shapes with a pencil or crayon similar to what you draw. Fine motor skills are also improved by teaching the child to use child-safe scissors.
Problem solving skills can be improved by asking the child to place objects of different sizes, texture, or color in different bags. Planning a treasure hunt with the child can also help with improving problem solving skills.
Finally, for the support of personal social development, one might instruct the parents to play dress-up or make-believe with the child. It is also advisable to let the child help at mealtimes.
Of course, not all of these activities can be done by children at any given time. Therefore, it is important to choose activities that are age-appropriate to the child.
