Last night, Brinson again got cold and had some greenish residuals on her feeds. Cold temp and green residual (slow gut) can mean infection. So, they made a decision to do a full workup on her.
She is also back under a warmer, sitting at 40% O2 and getting 2 different antibiotics.
One possibility is, since she is not acting sick, it could be Brinson not tolerating the breast milk feeds and they may have to change to formula.
The good news is whatever it is, we caught it early.
