What kid doesn't like Cheerios? I don't know what it is about the wholesome cereal bits, but my daughter goes nuts for them. So when she's stubborn at feeding time, I pull a fast one on her. I'm not big on tricking my babe, but sometimes it can get you on the right path.
For the trick, sprinkle Cheerios in front of baby. Then, when she grabs for one and opens her mouth to eat it, slip your spoon full of yogurt or veggies in before she gets the cereal. Most times, your bunkin will be none the wiser and take both the bite and the Cheerio down all at once.
If that doesn't work, another option is to put the food on the spoon and top it with the Cheerios. After a couple of bites, she'll just take the food sans the cereal. And, you'll have a well fed wee one.
