first of all, plain rice cereal made with formula/breastmilk, or water tastes like wet cardboard, so i'm not surprised he doesn't like it. that's something you can add to the bottle, or any food, but there's no reason to make it runny. he can handle some texture at this age. continue to offer the food. experts say it can take up to 15 times of tasting before they actually begin to like a new food. why not give him table food? at 7 months, there is no reason he can't eat table food. i started my daughter on 2nd stage food (we bipassed the 1st stage all together) when she was 8 weeks old. i put rice cereal in her bottle at 5 weeks. by the time she was 5 months, she was eating table food, and taking a bottle. i started out with veggies, not fruit. luckily, my kid ate anything you put in front of her. i think a lot of that had to do with starting early. she still eats like a champ, and she's 22 months. gerber makes all kinds of yummy jar food, and the pasta pick ups are great. raviolli would be a good choice for him. i know, because i have tried them myself. these were some of her faves:broccoli and cheese, bananas, apple blueberry, spring vegetables with wild rice, chicken noodle, sweet potatoes, spinach, plums, butternut squash, peaches, and vanilla custard pudding with bananas-that was a rare treat for her.she loved all the ravioli, and her favorite seemed to be the spinach cheese.if he likes sweet potatoes, then you can buy acorn or butternut squash in the produce aisle, and bake it with butter and cinnamon. cut it in half, scoop out the seeds with a spoon, add a dollop of butter, and a dash of cinnamon. bake at 350 for 1 hour, or until soft. also, i cut up yellow squash and zucchini top it with olive oil, and fresh shredded parmesan, then bake until soft and golden brown. she gobbles that up like candy. i hope this helps. picky eaters can be soooo frustrating, or so i have heard. i was a super picky kid, and still am today. i'm thankful that my kid hasn't taken part in that.
