She’s drinking, eating and pooping but it seems that she’s having trouble standing for long period of time. If she needs b2 how much does she need and what is the best way to administer it? I don’t know how to check for swelling of the abdomen. I don’t see anything abnormal with her other than sitting a lot . She was always the one to be under the heater more than the others and she was very tiny. Thank you so much for your help.
