I started my son on "real" food. I cooked all his food and then pureed it to the consistency the needed at the time. The transition to our food has been quite easy. Most of the time he eats what we eat now (he's 19mo) and has been since he was about 14mo. He has a severe egg allergy so there are foods still that we haven't quite given up and just cook something extra or slightly different for him. For example last night I made beef strognoff I usually make this with egg noodles, but for him cooked a separate pasta that's egg free (a little more expensive too). He didn't know the difference and for the most part was still eating what we eat. Of course there are a few foods we still haven't given him like shell fish and nuts...but other than that he pretty much eats what we do.
When I cooked his food, I cooked in mostly in bulk and froze the left overs in ice cube trays so they were portioned out. All I had to do was take as many cubes out and thaw them out (20sec in microwave). This way I could mix veggies easily without always keeping them that way. He loved it!!
If you started her out with "real" food then be patient...she'll catch on. Just keep working on the consistency of the food, making it a little more and more solid. If you started her out on jarred baby food, you could just take the jarred baby food away, cook a few meals for her and puree them to the consistency she likes, and then go from there. She'll catch on. If you don't feel comfortable with this...be patient..she'll learn to eat what you do. Remember there's aren't any 3yr olds out there still eating jarred baby food!
