Not Growing as hoped

Our first couple weeks home, was great! However Erica started to slowly refuse to eat her bottle. We have been going into Pediactric Out-patients twice a week for blood pressure checks, oxygen saturation check, and weight checks. If Erica couldn't continue on gaining weight nicely she would have to be re-admitted to the hospital, so weight gain was extremely important. However within nearly two weeks Erica hadn't gained anything.
