I agree with Whiskers too - just slowly try to wean off the jar food. My daughter just turned one and I still give her the stage 2 fruit with her breakfast or occassionally a jar veggie with dinner if I haven't steamed her anything to be sure it's nice and soft. I have been very slowly incorporating solids into her diet, but I'm also always worried because she crams lots of food into her mouth at once! At least with some of the jar food, it helps wash down the chunks in her mouth.
I'm not worried that she's still on the jar a bit because I think the switch to solids can be a slow process sometimes. ...and now I worry about when she's suppose to be able to use a spoon!

It never ends!
