My toddler won't eat his veggies...yes, I've tried repeatedly with various items. A friend suggested making smoothies and putting veggies in it. I poo poo'd it (to myself) until I FINALLY tried it last week. Needless to say, he's had (AND FINISHED) smoothies every day. I've given him kale, spinach, carrots, and sweet peas so far.
I now buy a bunch of frozen fruits, berries, and veggies and keep them in the freezer. When I feel Mr. Picky needs a shot of veggies I make him one of these smoothies and he usually gobbles it up. However, depending on your child and which combo you choose to put in there he may reject it. Experiment and enjoy!
