What else can I do for my colicky baby?

I'm a new mom, my daughter is 8 weeks old, she's very colicky, and we desperately need an answer. After 41.5 weeks of pregnancy, I had an emergency c-section with her and was pumped full of anti-biotics beforehand. She has been on Nystatin for a month for thrush. We tried many different formulas (my milk didn't come in) and has been on alimentum for 3 weeks. By the time she was 2 days old she was ping formed/hard stools. The pediatrician has tried her on miralax and lactulose however it did not give good results. He sent us to a pediatric GI doc at Children's Hospital to rule out stenosis and Hirschsprung's. We used infant suppositories until the GI doc told us she would become dependant. However, she could go with that stimulation. He seemed to think that everything was normal and that she just needs to learn to poop on her own. She spits up alot, and doesn't want to eat when she doesn't have a BM. She grunts for hours, and has alot of gas without results. Please help!
