During Audrey's last Dr. visit, the pediatrician let us know that we should start Audrey on solids within the next couple of weeks. I thought it was best to progress to solids by introducing RICE cereal. You add it to formula/breastmilk. I didnt want to start Audrey to quickly on solids because i didnt want to hurt her. Now that shes being introduced something other than liquid, her bowel movements will also change to a more solid substance. I didnt want that sudden change to hurt her little tummy. So for now Audrey is satisfied with Rice cereal in her formula and It has helped a lot in making her more full. She loves it, but a little at a time ;]
