my fault! Not sure why I read your post as you guys already being in Thailand (and your husband traveling to Jakarta). As someone with young kids at home, thanks for the post!
"What’s the easiest way to get a DTV visa in Thailand?
You CANNOT apply for this visa while in Thailand. You will have to return to your country of residence and apply through the Thai embassy or a participating consulate."
We were previously on volunteer visas (for an actual foundation, actually volunteering) pre-Covid, and everyone was considered a "follower." Wasn't sure if this would be similar or not.
