Children's rooms have always been a focal point for parents and society. Creating a living space for children that is conducive to rest and sleep, independent study, and is both safe and healthy as well as fresh and natural, while also helping with the physical, mental, and intellectual development of children, is an issue that parents particularly value. How can we create a personalized and practical children's room for our kids? Currently, most parents have some misconceptions, simply thinking that buying some children's furniture is enough. However, this is not the case. A true children's room should not only have a reasonable layout and suitable furniture, but more importantly, it should be designed according to the child's growth stage. For this reason, reporters interviewed several well-known home decoration designers in Guilin City and summarized the key points of children's room decoration design for different age stages.
