I am going to start LO on cereal soon and not sure if I should skip the rice cereal and go straight to the Oatmeal or barley. Pedi said it didn't matter if we did rice or oatmeal first. She has constipation issued so I am not sure if I should skip rice. Pedi does not want us starting any fruits and veggies until her 6 month appt. What are your opinions? I am not however waiting to start cereal until 6 months. We will wait another week.
