hi
sorry but i believe you may enjoy having the freedom of having wheels ...
We have arrived in Sg at the end of march with 2 kids (7 and 5) and me being quite heavily pregnant. Our
condo is very central , picked thinking we would not need a car but after a few months here, struggling now with newborn in car seat and 2 boys, we have given up and bought a car. Firstly, you never know what kind of driver you are getting when you get a taxi but mostly the commute to the school for the boys was far too much. The school bus does pick them up at the door of the condo which is great but they are the first picked up at 7.10 am for a 8.30 start and the last dropped off at 4 pm when their school finishes at 3 pm. A very very long day for them. With our car, i can leave at 8 am ! Now we can have more freedom after school for my eldest to do ECAs ( not so tired anymore) or meet up with their friends. Taxis are cheap but when you take them everywhere, it does add up too.
This is only my personnal experience , I would recommend you keep an open mind and see how you get on after arriving. We just decided it wasn't worth struggling for months to get one anyway. Best of luck.
