They say that if you keep offering your child a food, she’ll eventually eat it. I can testify that this is true! Sweet Potato has never been much of one for broccoli- at least not the florets. She’d nibble on the stems, but that was about it. But I make a point to serve her florets along with the stems, and she has started eating them! She even went for them first when I made her a quick lunch of broccoli, chick peas and mini penne.
Another food that she wouldn’t eat (inexplicably) was raspberries. She’d eat blackberries, and loves strawberries, but consistently turned up her nose at raspberries. But one day when I was eating them in the kitchen, she was grumpy/ hungry, so I gave her one. She ate it and wanted another. She ate as many as I would give her. How about that? Maybe the trick is not only to offer the food multiple times, but to eat it yourself, while not offering your child anything. Let your child’s covetous nature work in her favor.
