My baby's doctor just recently recommended to put her on rice cereal do to her acid reflux. She spits up constantly to where she can hardly keep her bottle down. the first bottle I made I put one teaspoon of rice in there and she wouldn't drink it. I had to pour it out and make her a bottle without the rice in there for her to eat it. This morning I decided to put half a teaspoon of rice in her bottle and she still won't eat it. Any recommendations should I try feeding it by spoon?
