If you’re thinking of the baby, you should plan for much longer than the few years of a DTV. The older a kid gets, the harder it will be to learn a new language, lose friends, and have a decent education.
Schools aren’t that good in Thailand and for a foreigner it hard to get a job (and work permit), plus a Thai degree is worthless outside Thailand. You better stay where your kid is a citizen (or in some western country, which got reputations for good education)
