When should babies learn to use eating utensils?

e-How.com showed me the way!  A little late, but next time Jude eats over, I won't need the carpet cleaner.  You see, if you scroll down to rule number two, you will read as I did, "Consider lining the floor beneath your baby's highchair with a garbage bag or plastic shower curtain liner to catch food your little one will inevitably drop or throw."  Now why didn't I think of that  before offering this newbie-fork-user, pasta with lots of tomato sauce?  Next time around, the curtain comes out and down, and I'll be lined with the garbage bag!
Ready and waiting,
Bubbie
P.S.  What tricks have you used to help your kids or grandkids use eating utensils?
