Foods at this point are to teach them how to eat and introduce them to different tastes and texture. They are supposed to supplement formula/breast milk, which have all the vitamins and nutrients they need till 12 months. You should give her the bottle and add the feeding around the bottle schedule. It should not replace a bottle feeding. Try to stick with your breakfast, lunch, and dinner that way she will be able to transition easier to your family meal schedule when it is time.
You should start with one food every four to five days unless there is a history of food allergies then one food every week. This will let you better identify if they are allergic to that food or not. If everything is good then you add the next food. Usually you start with rice cereal, then oatmeal, then orange veggies first, then greens, then fruits etc. Meats are usually added at 9 months but ask you Ped, some start at a year. When adding the new food try it at breakfast or lunch instead of dinner due to if they are allergic you can respond and/or notice it before they are put to bed. Also if it does not agree with them they won't be up at night with pain or gas.
When you start with the rice cereral it should be very thin, formula consistency, then as she gets used to it you can make it thicker. Babies have a natural tongue reflex action that helps them from choking on things that they should not have in their mouths. You will see it as they tongue everything out that you put in their mouths at first, this is why you start out thin and get thicker as you go.
Hope this helps
