I read of an article a few weeks ago. One couple has seven kids in Singapore and their monthly expense is about $3,000 to support a family of nine. Please see below for more details
Based on the above information, it appears that the couple also needs some assistance from the Government. In addition, one parent is the sole-breadwinner of the family. I am not sure whether this is a strategy from the Singapore Government to encourage more couple to have more children. I believe that it is up to the other couples to decide on whether to adopt such approach. To each of their own.
