Copied from your other thread:
I live in Bangkok, moved when DD was 2.
Lots will depend on the circumstances of the move - are you being relocated by your employer, because if so, most will offer relocation advisory services.
If you are doing it independently, then you have more to figure out yourself - eg do you want to ship stuff, or only bring what you can take in a suitcase?
Re jabs, I kept my red book from the UK, and put vaccinations in my diary, so that I could book the same ones in Bangkok - cost is high on medical sometimes though - do you have decent cover?
Speak to your GP about jabs - you really only need the same ones you would have if you were going on hols. Malaria I don't think is needed - KL is malaria free (and its not a jab, its tablets, so you would have to take them all the time, which is not good for you - insect repellent is far more appropriate).
Some things you will want to think about might be, for example, cost of schooling - if you are not sure of whether the move is permanent, you will need to keep DCs in the UK system, and British schools in Asia can be eye-wateringly expensive.
Do you have jobs lined up? Its a goldrush in Asia with lots of people trying to move out to escape the EU recession, and an increasingly skilled and educated local workforce, so don't assume jobs are easy to find, they aren't.
If you do have jobs, then ask the employer concerned to provide you with contacts in-market to help with relocation/local advice whilst you are planning the move.
