try staying near to International Schools
near your kids prospective choices. It save on beating the jams, traffics or long distance (well not that far as the states but nearer is always safer and better) walking/driving.
Bukit Timah is a good area for living/food/transports out to town and there are many condos
/apartments/flats/terraces/bungalows and etc in this big area. Secondly, there are many locals/expats living in here in harmony, food are accessible too.
If you like nature, Botanic Garden, Bukit Timah Hill, River Safari and etc are not too faraway too. West Coast Park is a place with Macdonalds and many families get-together on a weekends, even weekdays.
Hollands is one good option too for venue too. Just a reminder that apart from Town area like Orchard, Holland and Bukit Timah are rated as one of the top few expensive living area.
There's a lot more to explore and decide for you and your family, here is just a little assistance. Hope it helps.
