Durain is right, pretty much everywhere is good. Best is to check out the local malls to see if it contains what you want, for me living within walking distance to Tanglin mall is a must, it contains all the toddler schools/play groups, kids toys, clothes, shoes, shops, a good supermarket and a food court. Often has kids shows.
Next door is Camden medical centre for all you kids medical needs. Botanical Garden are a short walk away. Just down the road is Forum again lots of kid orientated shops.
Living in a condo
is fine, just make sure its one with a bit of outside space. You have a ready supply of playdates, and when you go on holiday you just shut the door. It all depends on what you are used to I was brought up in Hong Kong my whole life was spent in condos
, I turned out OK
Perving on your neighbour is an added bonus, the one opposite us leaves all the bathroom blinds wide open!! Always a high point during our dinner parties.
