By the sounds of it - she is a very healthy girl!! Oh my goodness. Definately continue to breast feed as often as she/you want to, but how about breast feeding after you offer solids??
They say you can exclusively breastfeed until a year.... so I wouldnt stress too much if she isnt into solids. She doesnt need them yet. She is CLEARLY getting everything she needs from breast milk, so I personally wouldnt force the solids.
What are you mixing the cereal with? If it is anything but breast milk, that could be why she is rejecting it.
I started my daughter at 4 1/2 mos with rice cereal mixed with breast milk. I did 1 tsp of rice cereal with BM until its creamy. Maybe the texture is bothering your daughter, try making it thicker or more creamy, warm and cold... etc. My daughter was so finicky - if it was off a temp or was too thick - she wouldnt eat it. Then I slowly increased the amount over a slow period of time so that she and her belly could adjust to it. Eventually, I fed her out of teh plastic container and just let her lead the way til she turned her head as if to say "I'm full". I gave her rice cereal at 4 1/2 mos and then waited until close to 6 mos before I had introduced fruits & veggies ( I introduced a new one each week). My daughter also liked the banana flavored rice cereal.
I dont know if this helps, but like I said - I wouldnt worry if she is having breast milk. Congrats on still breastfeeding!
