Moms I encourage you to do tons of research if you have at doubts about a portion of your care or your baby's care. Please keep in mind that unless you actually read the medical journal the specific research is in you may be getting a summary and the opinion of a second party on the subject. I am all for research and have done plenty of it both in school and now. I am a Registered Nurse that works with medically fragile children. Some who had noted issues while still in the womb and some that had issues they did not find until after they were born. This last part is obviously not meant to scare anyone.
