Skipping oatmeal/ rice cereal?

Any one else skipping the oatmeal and rice cereal? I'm a ftm so I'm not really sure what I'm doing, but I've read that neither provide any "real" nutrition, and that the rice cereal is just downright bad. I haven't started my 5.5 month old yet but I just bought some sweet potato and carrots to puree for him, would it be okay if I only have him fruits n veggies? (and bm obviously)
