You've already gotten good advice. I just wanted to say that my twins gagged on anything that wasn't pureed (1st or 2nd foods) until they were 12 months old. Even the 3rd foods, some of which had grains of rice in them, would make them gag. It took them a while to get the hang of chunkier textures, but they eventually got it. I think some babies are just different. Try not to worry!
