HOneslty I have to say that it sounds like NEC. Yes we have experience with this as Michael was diagnosed with NEC. He was at a NICU near home, just 13 beds, and about 3 weeks into his life they were having issues with him digesting food, etc. They suspected NEC right away,called us at home at 12am, rushed him via amublance to another NICU in our state. I had no knowledge of NEC and honestly I'm glad I hadn't read about it or else I'd have been a wreck. Many babies die from this is the meds don't work, the surgery is very invasive. Luckily the antibiotics worked and after about 7-10 days they resumed feeding breas milk, he was transfered back to NICU at home and then 2 weeks later came home. He's not had any digestion issues at all...and he is now 22 mos. She will be fine..he had no replapses.
