Hi, my son was the same at 7 months. I found that he wanted solids, not baby food anymore...only he had NO teeth! He not only wanted whatever we were eating, but he wanted to start feeding it to himself. He still goes through a few bites off the spoon, and then refuses because he needs to feed himself. I bought canned vegetables and rinsed them off, same for fruits. It's a lot cheaper than baby food with about the same quality. He loves green beans, so those I like canned because you just can't get them soft enough unless you boil them forever...then they really are no different from canned. If you have time, you can buy fresh and steam them or cook them so they are soft enough to mash with the tongue and swallow. He also loves bananas. I break a chunk off and he can pick it up and feed himself...just make sure they are not too soft or they get REALLY mad when it mushes in their hands instead! I also bought low-sodium soups and break one can into three separate bowls to feed him. The foods are really soft for him and he get's chunkier foods that he wants. I hope that helps, I know I'm always looking for ideas of foods to feed a toothless child. He'll be 1 in a few weeks and just barely cut his two bottom teeth. You can see them, but they aren't up all the way yet.
My friend has a son that is 1 1/2 years old and he is the opposite, he doesn't want any regular food, just baby food! To each his own!
Good luck & hang in there. You may want to check for teething, they all seem to lose interest in eating for a few days when they are teething.
