In Singapore nowadays, it's very common to have a maid, especially if you have kids.
Many families are double income families, meaning both husband and wife work.
But there are also many newly married couples who don't have a maid because they're just starting out. With a new HDB flat to pay for, kids are probably planned for the future. Young couples often have to take care of their homes themselves. Hopefully, you have a husband who loves doing chores all by himself. Yeah, dream on.
