Media is increasingly available to children and offers more and more content and it is increasingly difficult to control what children are doing, seeing and hearing through the media. Nowadays, children are very early on in computer science and can access the Internet themselves or turn on computer and television. The impact of electronic media on child development has many advantages but also disadvantages. Before providing a content, which child will use through electronic media, it is necessary to study the content well and to see how much the child will use it. There is no equal effect on the media on all children due to factors such as age, gender, socioeconomic status, etc., which increase or decrease their impact. The use of electronic media in kindergartens/schools greatly improves educational work because a certain topic can be presented to children in a more vivid and interesting way. Children are increasingly spending their free time with electronic media instead of socializing with peers and families. This harms their physical development, health in general, social development and linguistic-language development. Media should be used responsibly and thus have a positive role. Mostly negative events are displayed in the media and children can get the wrong perception of the world. Important people in a child's life are parents, so they play an important role in using electronic media, such as the content the child will see or to talk about content that helps track what a child is looking at. An example of different education of the child is presented in this paper, without the use of electronic media for certain years of life. The Waldorf kindergarten/ school has a different view of the use of the media and the children only meet with the computer in the higher classes of the school. People communicate by speech, and to develop it neatly requires a well developed speech organ, good health, sound hearing, neat intellectual development and stimulating environment. A child with one touch of the switch has a great access to a variety of media. Almost every child in their household has a television and a computer. If the child is completely banned from playing games or television, he/she will not be able to participate in conversations with his peers on the media. Excessive use of the media may cause a smaller interaction with peers, and thus lessened the language development. Therefore, it is necessary to choose the media through which the child creates useful educational experiences and advances in their linguistic-language development. Television can have a positive impact when learning another foreign language. It will not fully help to master another foreign language, but hearing and visual support can be useful for learning a foreign language. The influence of television on linguistic-speech development can be positive if the child is watching television for appropriately long period of time and if he understands what he is watching. Various studies have shown that a child who is watching television longer has lower language abilities that include length and complexity of sentences and reading skills. Excessive use of computers by children disassociates them from peers with whom they should develop social language skills. Video games are modern and popular types of media that are especially popular among boys. They can be useful for fine motor development and visual-spatial perception. Video games do not encourage speech-language development unless they play in the interaction of two players. Parents choose a child-friendly game with their child and participate in the game together. Video games can easily create addiction in children and thus dislodge them from peers and make them work less on their language development. An adult is important in relation to the media and children. Talking with a child is important in general in the upbringing and even in the use of the media because talking about what the child is watching, what these actions are and what they are like compared to real ones can enrich the speech-language development and can prevent unwanted situations in a timely fashion. In this paper, a study was conducted on the correlation between the use of electronic media and development in pre-school children. The results show that the only over-use of television and tablet is associated with the deviation in speech-language development. Overuse of television can be also associated with a group of children who use the media without adult supervision that who watch television alone as well as or talk very little about the content they have seen.
