How much do you usually give your baby when introducing solids. I've been offering her about a little more than a tablespoonfull of rice cereal for about 2 weeks, once a day. She still seems to want more when we are done, but I top her up with nursing, she also has about 4 gulps of water to wash down the cereal. Is this okay? I wanted to try sweet potato next. Am I feeding her enough solid or should I feed until she refuses anymore?
