What is the best visa option for a family entering Thailand with a child who may need a Thai passport?

Hello,

Before the question here below, just want to say thank you for all the clever advice that we can find here. I think we don't say thanks enough to the admin from this page.

Back to the point :

I have a similar situation from the one exposed by Brain Barton few months ago although in my case is slightly different:

- I have a work assignment in Thailand that will kick anytime soon.

- Miss cutie Canadian mix toddler and her Thai Mom are following.

The question is strictly for miss cutie:

- I still haven’t determined under which Visa approach I will enter Thailand. Would it make more sense to enter under the Non O with the whole family instead of going through the process of the non-B. What would be the less painful way for miss cutie?

- In the case we’re going to the path of having Thai ID/Thai passport for miss cutie once we’re in Thailand, will she need travel out after 90 days with her entry passport and re-enter with her Thai passport? (we believe that doing it while we're in Canada might take too long)
