Re: 5 wk old rescue not eating
It is hard to fully hydrate a baby in a few hours. Can't tell from what you wrote what her hydration level is. Make sure you continue to hydrate between feedings. 49 g for 5 weeker is pretty tiny. Did you transition her to formula so she would not bloat or get diahrea? Also, if she is 5 wks, feeding her every two hours is too often. I don't feed a Pinkie that often.
Slow and steady wins the race, there is no hurry to get them back to proper weight. You will end up giving them diahrea, then you will have a real mess on your hands
