Are you wanting Benny to switch to a "regular" water bottle (as opposed to a crock or bowl)?

If it's a "regular" bottle, the switch might be fairly easy. Try substituting the nightly bottle for the new bottle (do everything the exact same way--but with the nw bottle). If he doesn't drink much that way you can always switch back and forth until he gets the hang of it. A way to entice him to drink from the "new" bottle--try smearing a piece of banana or some pineapple juice on the end!

Hope that helps!
