Thank you for reaching out to the Wefugees Community.
What happened to you is indeed strange and confusing. In order to have a chance to understand/estimate, if your child actually fulfills the requirements for the naturalization, it will be helpful to learn more details about the overall (residence) conditions and circumstances of the family. As I am not really experienced with the naturalization procedure, I will link two of our experts here. Dear @mbeon-Christine or @mbeon-Rukundo, can you maybe share some more information or ideas on this case?
I can also recommend you to contact a migration counselling office for support and clarification. Please let us know if we you need help in finding a respective office close-by.
All the best,
