My son is 17 months and has been on zero milk or formula since around 12 months. We were weaning him already, but he went cold turkey by himself after he caught a 24-hour stomach bug and vomited milk all day... We started with blended foods around 6 months I think, and added in small solid foods once he got teeth. At this point, we give him whole berries or veggie chunks and he'll take small bites and munch it down. He's getting some molars breaching now; once they fully emerge we'll start working on chewing larger pieces. I should probably not be as excited about this as I am...
