Really depends on what you are looking for (number of units, size of apt, facilities, cost..etc) but with that being said when you do your search online look for any that have a children's playground or childrens pool. I looked at almost 50 apts this last go round and some of them we really liked the ammenities for the kids and the number of children around the complex (Duchess Crest, Chancery Lane, Kerrisdale, Kew Green, Pebble Bay, Tanglin Hill, Tanglin Park) - but then the unit was too small or the location wasn't ideal or there were just too many people. Again, it's a really personal choice. We ended up in a place two months ago in an ideal location where there weren't a lot of children and the plaground/pool weren't great - but then in the last month 3 new families have moved in with kids our age so it's fantastic. Will you have a car? I think that can make a big difference on your decision as well. If you have a really large budget there are
condos like Ardmore Park, Claymore, Nassim Jade, Scotts 28... etc that have a lot of children (I do a baby group that rotates houses) and they are really nice. I'm sorry I couldn't be of more help - but there are so many
condos in Singapore it's hard to say what's best.
