Generally speaking, children's toys are designed and manufactured for children of a specific age group, and their characteristics are related to the age and intellectual stage of the child. The use of children's toys is premised on a certain adaptability. In my country, the age of children is limited to 14 years old. As a children's toy, it has a key factor, that is, it must attract children's attention. This requires toys with bright colors, rich sounds, and easy-to-operate features. It is worth noting that because children are in an unstable period of continuous growth, they have different hobbies at different ages, and generally have a mentality of liking the new and disliking the old. Therefore, children's toy stores should subdivide toys according to children's age groups: such as 0-3 years old, 3-7 years old, 7-10 years old, 10-14 years old, etc. In terms of their materials, common children's toys include wooden toys, metal toys, plush toys, etc. In terms of their functions, the most popular toys for parents are the toys that develop intelligence. Toys such as dolls, houses, furniture, cooking utensils, various means of transport, hospital utensils, etc., can be used for baby's role play. In the role play, the baby mainly uses language to express the plot and content of the game, so it can promote the development of the baby's language ability. For example, in the "play house" game, let the baby imitate the mother, coax the baby to sleep for a while, and feed the baby for a while. The development and change of each plot in the game can allow the baby to imitate the language and actions of "mother", which is much better than bluntly teaching the baby to imitate. Headdresses, masks, puppets, image toys for tabletop performances, etc., can allow the baby to perform games and play a prominent role in the development of the baby's language. Acting games can allow babies to use the language in the works naturally during the performance process, and thus master the correct use of language and creative intonation and expressions that match the character's character. On this basis, parents can also inspire the baby to make props for the performance game, which is very helpful to improve the baby's language expression ability.
