It is very important that our children develop confidence in themselves to face a world full of challenges. Children face a world full of challenges every day and this can make a little one feel somewhat insecure. At three or four years they have to compete with their peers to be able to make a dent in friendships and they need to strengthen their self-esteem to do so. Sometimes children can feel more withdrawn or distrustful when it comes to entering the world, something that could make them stand aside and not discover all the good that there is in the world for them.

The confidence of children themselves will help them cope with complicated situations in the future without fear. The environment at home and genetics shape the way of being our children. Genes are unchangeable structures, but aspects related to the environment do depend to a great extent on us, parents, especially in the first years of children's lives.

Reading and writing are essential for the correct cognitive development of children. These practices are responsible for developing language, increasing vocabulary, and improving spelling. In addition, they are a mechanism for transmitting knowledge, ideas, and opinions, therefore, they are instruments of the utmost importance for every child in the process of knowing the world.
