When we were young and life was carefree, we always had our mothers and father or guardians to seek out play things. Usually age appropriate toys to encourage socialisation and dexterity. This usually referred to physical development during early years.
But as time goes by and we develop into primary school goers, do we still need encouragement from parents or guardians to help with cognitive development. I would say YES as no matter what stage our learning capabilities lay we should always learn at our own pace and get help from seniors.
Seniors play a key part in our development in terms of what is and what is not allowed to be done. This is usually taken from the bibles commandments and what society needs to be good with one another.
We are NEVER WITHOUT learning new skills.
If you would like to know the main key elements from learning then PILES is the acronym for Physical Intellectual Language Emotion and Social skills.
