In a section on the 1949 Geneva Convention IV, the manual states:
Children must receive the care and aid they require by reason of their age or for any other reason. All practicable measures must be taken … to ensure that those who have become orphaned or separated from their families as a result of the war are not left to their own resources and that their maintenance, the exercise of their religion … are facilitated in all circumstances. 
Mexico, Manual de Derecho Internacional Humanitario para el Ejército y la Fuerza Área Mexicanos, Ministry of National Defence, June 2009, § 215.
In the same section, the manual also states:
As far as children are concerned, it is provided that the occupying power, with the cooperation of national and local authorities, must facilitate the proper working of all institutions devoted to the care and education of children. It must take all necessary steps to facilitate the identification of children and the registration of their parentage. It may not, under any circumstances, change their personal status.
