We tried the jarred meats with our first child but they just smelled badly and he turned his nose up at them. I think we wound up skipping the single meats altogether until we got to the stage 3 foods where they have meats/veggies/pasta all in the same jar. He really liked those. Now at age 3, he is pretty adventurous and tries lots of different foods, including meats and fish.
With our current baby who is nearly 8 months old, we just skipped the meats and stuck with the veggies/fruits and have recently started stage 3. We figured the first boy turned out okay so this one probably would too.
Give the stage 2 meats a try if you'd like and follow her lead. She may love them or she may hate them but if you want to introduce them, there would likely be no harm. I will warn though; in my personal opinion they smelled just absolutely awful! Not trying to be negative, just sharing my experience. I really couldn't deal with the smell!
