My friends' nearly 2-year-old son does not like green foods. (Except for guacamole, which I cannot account for as this food disgusted me when I was young.) This is not unusual for individuals in his age group....or any age group for that matter. :-p Something about sticking something green in one's mouth tends to be unappealing.
His mom has been devising ways of getting him to eat his greens. She said she was going to try adding shredded zucchini to his bran muffins. It is nearly invisible and the flavor entirely disappears. This method has been successful for me in the past with my siblings. As long as I keep it a secret as well. Because as soon as they know it is in there, they can't handle chomping down on something they know contains a substance they don't like. Even if they can't taste it. Weird.
I was eating pasta the other night at my friends' house which included in the mix some small pieces of zucchini. Their son was systematically fishing them out and setting them to the side of his plate. At least he was polite about it. ;-) She had also surrepticiously used tricolored fettucine noodles. He failed to notice the first few bites, but then became aware of the malicious color infesting his plate of food and began selecting bites around them.
Next day, when he asked for a 'nack' (snack), she served him up a plate of leftover pasta, this time run through the food processor. No luck removing the greens. Mom had outsmarted him this time around!! ;-) He was a bit frustrated at first but his hunger got the best of him....
