Cost of living in Dubai?

Hi all.

What is the general cost of living for a family "husband wife and 3 kids under 7 years of age" ? Back home in Cape Town we are renting a 3 bed roomed house in a good suburb, we both have cars, the kids all go to daycare full day and school half day for the older one. What will the Dubai equvilent of our lifestyle here be over there??? Just trying to get a general idea. We are both working parents

If any South Africans can help Id appreciate it! : D
