Hi bondbabies,
It is definitely doable without a car, but that all depends where you live and work. We love having a car after our first 2 years without one. I hated feeling car sick from the crazy Taxi drivers!
I recommend living on the East Coast (Siglap or Tanjong Rhu areas are really nice) and good schools to check out are Eton House, Chatsworth and the Australian School. All
International Schools offer mini-bus services that collect from and deliver the kids back to your
condo. There is an Aunty on the bus that helps the little ones buckle up etc. You can also research BusPlus service to take you to work.
Take your time to find a good helper. The maid agencies can be hit and miss as their popularity depends on how generous their referral bonuses are at the time (I can ask my maid which one is flavour of the month if you PM me) I have had great service from Joy at 121 Personnel Service. But I also went to multiple agencies to ensure I had a good selection of helpers. We ended up with a Filipino (better English for the kids) who had worked for local families for 8 years before us and 4 years on we are all still very happy.
Regards
TB
