Is it okay for my child to enter Thailand using a Singapore passport, and do I need to bring a birth certificate for my Thai wife?

The user inquires about entering Thailand with their child who is a dual citizen of Thailand and Singapore, specifically about using the Singapore passport for entry and whether a birth certificate for the child is necessary. Comments suggest that entering on a Singapore passport is acceptable, as the child would be treated like any other Singaporean. Additionally, it is advised that carrying a birth certificate may be beneficial when traveling alone with the child to avoid any potential issues, though it is not always requested.
