Whether or not to puree it depends on a couple of factors. The important ones I would be looking at are the number of teeth your daughter has and the consistency of the meat you are serving.
My son has been eating meat since he was about 6 months old. (He is the third child and his siblings didn't have reactions to food. His doctor had us start him on baby food at 4 months old.) If it is ground beef, turkey or chicken, then it usually breaks up easily enough and is chewable with gums. I wouldn't puree those, I would just break them up very small. Chicken, I usually cook by boiling in chicken broth with spices. We then use the broth to make soup or rice. Occasionally, I will use the broth to cook noodles, drain some of it off and add cream of mushroom soup to it. My 8 year old daughter calls this scrumptious sauce. When the chicken is boiled like this it is very tender and almost as easy to gum as the ground meats. I have both just cut this up very small and pureed it. When I pureed it, I added some cooked carrots and noodles or stuffing. This way it was a stuffed chicken stew or chicken noodle stew. My son really enjoyed it. He enjoyed it so much his older brother (4) and his older sister (8) asked to taste it too. I then had to do the same with their meals that evening.
Until they can chew (and will chew) more thoroughly, I would avoid pork roasts, pork chops, steak or roast beef that isn't pureed or shredded very finely.
Turkey if cooked moistly and not dried out, breaks up nicely and is easily gummed. Ham is another choice that is fairly easily gummed unless cooked til it is hard or dry.
Which you start with is completely up to you.
Anyhow, I hope this helps. Good luck with your little girl.
