Hi A.,
I started my daughter on fruits. I think it is perfectly fine to skip the cereal for now and go straight to vegetables or fruit. The rice cereal doesn't have any inherent nutritional value. You just need to make sure your baby is still getting iron. The cereal is iron fortified. If you are using formula that is iron fortified, you'll be fine. If you are using breast milk, you'll need to find another way for her to get iron, since the iron supply in your breast milk is gone at about 6 months. Sweet potatoes are high in iron and an excellent first food for babies.
I agree with others that making your own baby food is simple and economical. If you do use store bought, I would take out a bit at a time like others said (at first your baby may not even take more than a bite because she is not used to it). When I use jar food, I follow the 2 day rule for anything with meat in it. For straight vegetables or fruit, I think it is safe to save it for 3 or 4 days, as long as it is refrigerated and has not been contaminated with your daughter's saliva.
