TLDR : Answer Summary
A user inquired about extending her visitor visa for 30 days in Thailand for herself and her 16-month-old twin boys. It appears she would need to pay 1,900 baht each for the boys' extensions as well. However, according to comments, while extensions are required, children under 15 do not incur overstay fines, allowing parents the option to let the children overstay without penalty.
