1Mix puddings and milk together, then add Cool Whip and sour cream to pudding mixture and mix well (by hand).
In large bowl, make layers of wafers, sliced bananas and then pudding mixture. Crush a handful of wafers and sprinkle on top. Refrigerate.
(I like to use one box of banana flavored pudding in place of one of the boxes of the vanilla pudding. Yummy!)
