Miao Yutong can't retrieve the baby information.

1. First of all, the uploading data of vaccination information is very large, and it takes some time. If the vaccination information of children is not found, the data has not been uploaded.

2. Secondly, due to the large amount of data, the applet is being adjusted, so the child's vaccination information can't be found.

3. The children's information entered in the end is incorrect, and the children's name and ID number are filled in incorrectly, so the vaccination information of children cannot be found.
