My DD2 is 6m1w old. We are on cereal and several purees. In lieu of rice cereal, have you tried baby oatmeal? It has a better texture and a bit more flavor than rice. My 6 mo loves it with fruit mixed in.
Fruits we are currently doing (and in order of her preference), include: pear, apple, peach, apple/blueberry.......and bringing up the rear, prunes. I am about to try mango. Oh, I also use avacado sometimes.
Veggies we are currently doing are sweet potato, squash and peas and carrots. TBH, she is not really a fan of the veggies. I usually mix them together with a fruit and let her eat it that way.
Currently doing only lunch and dinner. Also, don't underestimate the impact of time that you are feeding her. I have found that if I try and feed her at 11:30 am, she clamps her mouth up and refuses to eat, but if I wait until closer to 1 pm, she is hungrier and much more cooperative. At first, I just assumed she didn't like what I was feedinf her, but often, it turned out to her that she was not hungry.
