Also, with spoons, try a metal one (I find the rubbery/plastic ones can be difficult to scoop with) with a stodgy porridge, or ice cream. Both these have an element of "stick", so once they get it on the spoon, if they turn the spoon over, it should still stick for a few seconds and allow them to get the food in their mouth.
DS now uses metal for his ice cream if we have it, and plastic/rubbery for his cereal (those are deeper so he gets some milk with his cereal, where as the metal is flatter, but better for "cutting" off bits of ice cream). Xx
