Gastroenterolo-what?!

Ok, so I know my latin as well as the next person, but I never thought I would have any need to visit a gastroenterologist, let alone have to take one of my kids. Gastroenterologists are medical doctors who specialize in the diagnosis and treatment of diseases of the digestive system, such as hepatitis, ulcerative colitis, Crohn's disease, and colon or rectal cancer. They also deal with diagnosing intestinal issues such as Hirschsprungs and Celiac Diseases. Tomorrow we will be having our first, and hopefully last, visit with the friendly gastroenterologist for Peanut. Since she began eating solids she has had constipation and related issues on again off again. This past weekend it reached a whole new level, resulting now with our pending visit. I am hoping that I am right in my motherly instincts thinking that she is just not getting enough fluids. Since she is breastfed, she really has no desire to take liquids (even my pumped milk) from a bottle, sippy, straw, or nosy cup. We have tried everything from thinckened liquids to jello, nothing seems to piq her interest enough to want to drink it. Therefore, I beleive that she is not getting enough fluids, so while she is not dehydrated, she may not be fully hydrated. I am also praying that the doctors are incorrect in their feeling that she may have Hirschprungs Disease. It is a disorder in which the cells inside the lower intestine that help move food along are either dead or nonexistant. Apparently this is more common in kids with DS, and must be dealt with surgically from what I understand. Chalk another one up for Peanut and her Mommy. I am starting to wonder if I should go back to school...after all I am developing a wide repitiour of all the different specialties (hoping I won't be learning about any others!). The things we learn about.....here's hoping for the best.....and praying for a less stressful week next week, as I am having a hard time this week. The appointment is tomorrow afternoon...YIKES!
