Neither of my kiddos would eat solid foods, as far as 'mooshed' foods, no matter what I did. I tried making my own mixed with breastmilk, with water, tried store bought, tried organic, tried non-organic. They never ate it. I found there was no reason to push it. They get it and want it when they are ready. Your breasmilk has all he needs, so there is no reason for it really. Many people don't even start them until a year. What I did was just wait until around 8 1/2 or 9 months when they could pick up and eat little pieces of food. They always enjoyed doing that and wanted to eat what I was eating. I also found they would eat flavorful liquid food, like cream soups, etc.... Take it slow, don't bother fighting a battle you don't need to, and everyone will be fine :).
Also, rice cereal has very, very little nutrition in it. Other things that are easy to digest, but taste much better and have much better nutritional value are avacados and bananas.
My kids wouldn't take bottles either. We went straight to the sippy cup when they were ready. Try a 'safe sippy'. They are very boob-ish and both my kids loved those the most. They are also BPA and phalate free, which is a huge plus.
