My pediatrician recommended Isomil or Similac. Carnation Good Start is a good formula, and if the child prefers this over Similac, for example, I see no harm in it. Sometimes children with this particular formula have gray color stools, but this is felt to be normal. Some researchers believe that Carnation Good Start is somewhat less allergenic than Isomil or Similac. If you have a child that has skin allergies, then this should be discussed with your doctor.
Some companies send free samples to patients and doctors.
The industry is very happy to get anyone to buy their formula, but breast still is best. Yes, it is true. There are a lot of other things about nitrites that aren't so great either. They cause headaches. The headache that your child gets that is blamed on being in the sun at the ballgame is really due to the hotdog they ate.
