I'll give you one word to start with, and we can work from there.....EXPENSIVE!

We live in a 3 bedroom condo in the central area (so very close to Orchard Road - think ridiculous amount of shopping) and pay about $6k a month in rent (singapore dollars) BUT that is included in DH work package. You'd definitely want that to be covered.

Things to do for kids.....Did I hear Play centre!! Swimming..... Play centre.....Swimming.....and ridiculously expensive extra curricular activities. Their parks don't even have swings

Getting around in Taxis and buses if you don't have a car can be a bit awful in the long term (well for me now we have DD) but buying a car is also totally ridiculously expensive (we just paid $61k for a car.....on finance!)

On the upside....you can get a 'helper' for about $400 a month...it helps them out greatly. BUT there is a hidden Maid's levy paid to the government at about 270 per month PLUS you have to feed, house, and insure them too.....not such a cheap exercise....but is the 'done' thing. I never wanted a maid....still don't really....

It is not a bad place to live though. Of all the asian countries you could be an expat in, this would be the one to do it. You'd definitely want it to be worth you while though. Because living here costs a bomb. I seriously paid $4.25 for 30g of Rosemary the other day!

There is much more to it though so shoot through your questions
