Baby food... need i say more?

My daughter is experienced with Gerber Stage 1 and even the fruits and vegtables of stage 2. She enjoys spoon feeding very much. i think that i started her too early, but then again she is taking everything fine and everything seems right. She has never had any allergic reactions or anything. Her bowels are fine, has about 16-18 oz of formula per day and two sittings of baby food. She will be five months on the 12th, and im really confused. One site tells me that I shouldnt have even started her on baby food till this month another site says that she is fine where she is at and that she'll progress how she wants. Another says that she can get diabetes from having baby food to early. Im so confused!! I don't know if its ok to continue what im doing or if i should wean her off just to put her back on in a month? When do i progress to stage 3? When are stage 2 meats and veg/fruit ok? meat by it self? juice? Thats another thing is juice. I was on gerbers website and it said that its ok.
