Visit Cambodia with Cambodian partner and our baby

[Jack 0009]

I'm looking for all information, even outside of the scope of my questions.

I am going to visit Cambodia several times with the idea of moving there eventually

I am retired here in Thailand for four years now on a type O-A visa my GF is Cambodian on a type L-A visa

our baby is less than two years old. I have American naturalization and an American Passport for her.

I can get a Cambodian passport I think as well for her but have not done that.

on my first trip I want to drive my car across the border. we want to cross in Trat Provence border crossing.

my questions are to do with driving with my Thai drivers license and taking my car across the border and back  

what issues I might encounter?

I plan to wait until Thailand eases more restrictions for re-entry so maybe July?

are there vaccinations we should get?

any thoughts would be greatly appreciated
