7 month old not eating a lot

My 7 month old just recently got introduced to foods with texture. She's been eating Gerber and beechnut jarred foods since she was 4 months and ate 3 meals a day on top of nursing starting at 6 months. But now she won't eat anything out of a container except yogurt. And the finger foods I do give her (avocado, eggs, teething wafers,bananas) stuff like that, she barely eats any of it. So she gets most of her nutrients from nursing, which is fine. I just don't understand why she's stopped eating like she was. Now I'm afraid she doesn't eat as much as she should.
