sounds a lot like my DD...she just turned 2 and she's eating *much* more than she was even a month ago. She, too, prefers crunchy foods. We do sweet potato fries (sliced thin, tossed with coconut oil and salt and baked til crispy), raw veggies and apples, cheddar and other hard cheese cut into cubes, homemade cookies and crackers made with whole wheat, flax, brewer's yeast, healthy oils or butter, etc.
We've also had luck with homemade popsicles...she won't touch a smoothie, but loves 'banana pops'--yogurt, banana, coconut oil, a little maple syrup. It took a few exposures to even get her to eat those, but now she actually asks for them (rare for her to ask for any food!)
