Education fund for Sarah

We're starting Sarah's education plan this month through AIA.  Ravi and I settled on AIA Insurance as the better and more stable company among the market right now.  The policy is to pay for her education fund until she's 18 years old.  In case something happens to either parents (death or PWD), the insurance will guarantee the balance and ensure Sarah will have it when she turns 18.  We believe it's better to start building children funds as early as one can.
