Nicole, Let us move with caution here and lets be realistic for the baby sake. If you were not satisfied with the medical treatment from the doctor by all means seek a second opinion from a "different" doctor as soon a possible. I would ask the new doctor if a flat plate x-ray of the abdomen would be in order to r/o obstruction. In the mean time I would offer fresh organic carrot juice (buy a juicer) for it is rich in vitamin A which the body can quickly assimilate and contains also an ample supply of Vitamins B,C,D,E,and K. It helps to promote the appetite and is an aid to digestion. Also only give the baby distilled water for it contains no impurities. Not purified,filter or tapp water never. Good luck and let us know what you decide. JM,RN.
