If you're looking purely based on interest rates, go for OCBC. Like Diana mentioned, it is a lot more convenient if you choose the bank where you already have a savings account with for added convenience. You can access the accounts online at one glance without having to log into another bank's internet banking page. http://sg.theasianparent.com/what-exactly-can-you-do-with-your-childs-baby-bonus-child-development-account-cda/

I would think it's the same since u cant withdraw money from cda account anyway.. But i use posb cause i got posb acc and i can do transfers via internet banking.
For me I use POSB because it can link to my own saving account which is POSB too. I vote for conveniency as there are more POSB banks nearby my place.
thanks
