Sometimes when you're first starting to experiment with solids it's hard to get food into baby's mouth. They want to play with the spoon, they want to play with your hands, they want to make spitting noises. This play is all good for baby's development.
Sometimes, however, you need to get that food in there. We personally want our own babes to both get at least a taste of each food we've prepared at every solid food meal because sometimes it can take ten or twelve tries before baby decides they like or dislike a certain food. If they don't want to eat it after that first taste we don't push it; it's never a good idea to force food on a baby. If baby knows that you're coming at them with a certain offender, though, sometimes you need a trick to get that first bite in there.
An easy fix: give baby a spoon of their own to play with. They have fun, they go to put it in their mouth and you slip in a bite of food along with it. It's minimally invasive and baby will tell you right away if they respond well to it or not. An added plus is the hand-eye coordination it works on, and pretty soon they'll start trying to feed themselves. And it's darn cute to boot!
(This is one of those things, like being in a high chair, that should always be supervised. It's amazing how far a baby can jam one of those tiny spoons in their mouth when you're not looking. We don't want any choking!)
