Last week Julianna had her 4 mo. well baby and ped said start rice cereal. I gave it to her once Fri and once Sun...then she didnt poop from Sun morning until Wed evening! She, like most BF babies, pooped several times a day normally! I called the ped on Mon and then yesterday and she recommended giving her some juice, which she hated! And when she pooped last night it was only a small amount and a thicker consistancy than usual, I had anticipated the consistancy change, though. She is crazy gassy too! Shes back to see the Dr. today, but I wondered if anyone else had difficulty when starting the cereal.
