Hi my name is Erica. I have a 13 month old daughter who has been exhibiting delays from birth. She has had feeding issues, apnea, breathing issues, as well as week muscle tone. She also is always fatigued, even after she naps. She also is exhibiting PICA behaviors. She is had multiple labs taken. She has had 3 elevated CK levels that have now gone down on this last lab, but continues to have elevated B-12 levels and elevated lactic acid levels. I don t know what to do now. Do you have any idea what might be causing these problems? Please help!
