Because most of the children accepted by the trust are young, parents have no time to take care of them, and these children need correct guidance in their self-care ability and study. First of all, the trustee can't just take care of the children's diet, but the nanny can do it. From the perspective of children's growth, we should cultivate children's good living habits, study habits and hygiene habits, and educate and guide them in manners, dealing with people, shaping their character and safety protection. At the same time, it is necessary to correct the child's special personality. In other words, children's autonomy is gradually improved under the guidance of the teachers in the custody institution. Secondly, we should have the opportunity to exercise our autonomy. Trusteeship institutions can set up some activities or games for children to do, so that children can gain some insights, understand something and improve themselves in participation.
