 So, when we talk about the stages of human development and learning, then the stage, second stage that is called the childhood stage. And childhood stage, when we talk about this stage, then we talk about the phases of this stage. And first of all, we would like to just discuss about the physical characteristics in this stage. So, physical characteristics in this stage are very prominent because now children are just shifting from the toddler hood and the infancy stage to childhood stage. So, this shift is new for the children and they have to just cope with the new changes that they are encountering with in the physical phase, in the emotional phase, in the social phase. So, in this stage, some theorists have divided this into two parts, in which they say early childhood and in the second part they say late childhood. For early childhood, the age period is between 3 to 11 years old or someone has said 6 years old or someone has said 6 years old. And this whole childhood phase is 3 to 11 years old. So, the physical growth in 2 to 3 inches is increasing every year with a very fast increase and in the same way, the increase in their weight. So, apparently, the physical changes are their height and weight. And in the same way, their mental growth is also increasing. Now, when they have cognitive skills in their mental growth, when they are improved, then their perception is to perceive and understand things and interact with them, then to intelligently resolve conflicts with them. All these things are coming into childhood. Now, the innocent period of their infancy is coming into a slightly mature stage in their childhood. And the two parts I have divided here, some theorists say that the first period of 6 to 11 years of age is considered late childhood. So, the story of the child at this time is that it increases and along with the weight and all the bonds and all the physical changes are happening. At this time, the child needs a lot of nutrition because the height and good health of the child depends on the good nutrition. Now, the child here wants to run and catch everything and they want to just run and they want to just catch everything and to just feel the presence of the different things in the environment. And after that, the first phase of their childhood begins to look a little mature and the babyish look of them starts to change. After that, the second stage of their late childhood, which we are saying that we divide the stage of this childhood into two parts. So, the stage of late childhood is 6 to 11 years or 6 to 12 years or 6 to 10 years. Different psychologists have divided this stage. In this, we also call it pre-adolescence because after this childhood, the next stage is of adolescence. So, because in 10 years, the children have better nutrition and due to their parents' genes, they grow quickly. Their height grows very well. If their parents had a good height, then their height also grows in the same way. Then, the children are more sharp. Their cognition is also working very fast. So, physically, they grow up with their early childhood and the factors behind them are better nutrition and their parental genes. After that, their home environment accelerates their physical growth by getting all these things. Now, where there is complete nutrition, where the parental genes were short-heighted by their parents. Similarly, if the child is born with health issues, then the physical growth of the child will be different. So, the purpose of saying that this stage is very important because the growth is growing very fast. And it is a little slow compared to infancy. But still, all the physical requirements of this childhood are starting. And the important thing in this is that the physical growth of the child varies. I have told you two factors. One is their parental genes, the other is their better nutrition. Apart from this, due to individual differences, two brothers, two sisters, one sister, everyone's height and everyone's health will be different. The third factor that I wanted to tell you was that if at the time of birth, the child had a complication of his health, then his physical growth will still be problematic. Still, his physical growth will be different from his siblings and his parents. He will grow with weak health and it is not necessary that his weight and height will be as big as his height and height. The same way, the same as his parents' husband or his friends or his siblings. So these changes in physical growth are normal. And it depends on which environment the child is concerned with.
