How Much Kmr To Feed Kitten?

I have a little girl kitten that I am raising on some dry food. She is about 2 months old and she has been eating it for almost two weeks now. I was wondering what the recommended amount of kibble to feed her would be?

Also, do you guys recommend feeding different brands at all? Because there are so many out there right now, and they seem to change their formulas every few years or something like that.. This thread might help me figure it out http://forum.animalpakies.com/showthread…14#post6894694
