Can anyone enlighten me… A bit confuse about this CDA account thing. My only son was born in 2006 and I received a letter to extend or opt out from the CDA account. My question is

1) Does my child qualify for the dollar to dollar matching scheme by the govt?
2) If he qualify then how much is the caps by the govt?
3) His CDA account only got $400 and is it too late to deposit money to get the dollar to dollar matching from govt if he qualify?
