What documents can I use as proof of location for my child under a DTV visa in Thailand?

When applying for a DTV visa for children, various documents can serve as proof of current location. Common suggestions from expats include a copy of the child's passport front page, a birth certificate, or a health clinic document that includes the child's name and address. Other options mentioned include a doctor's letter confirming an appointment with the child's name on it, or a banking document if the child has a bank account. Additionally, flight bookings into the country of application may also be acceptable.
