Thanks so much for your replies.
We are actually married so I don't think we'll run into the dependents problem.
The salary is before tax so I'm guessing it would be about 15-20% tax off that. Utilities, flights home are added on to the package, we wouldn't have a car but from what I've read that wouldn't be such a problem?
We would rent our house out here to cover the mortgage. I havent even started looking into the practicalities of this so this could be a headache!!
We're not entirely sure when we might have to go but I think it would probably be about 6-8 weeks after the baby is born - with the caveat that if the birth is traumatic or if the baby is ill then I would stay here in the uk for longer and join my husband later (not ideal for either of us as the plane trip with my wild 2 year old and newborn on my own brings me out in a cold sweat!)
We would get a family flight home once a year and my family have said they would visit once a year. I do have a tendency to get very homesick so I'm worried about this. But on the other hand, if we decided not to go I'm afraid we'd miss our opportunity to really make a change in our lives as at the moment, husband has no work/life balance, I'm sick of my job and we are both jaded and knackered.
If I wasn't feeling so unsettled and pregnant I think I'd be jumping at the chance!
Can I just ask whether anyone knows about how childhood vaccinations work in Singapore?
Thanks for reading, your advice is invaluable.
