GRIPE WATER.The numbers looks difficult, but I see you are measuring thrice a day... And the overalll tendency is raising, but a little slowly.
the 36-45 means probably 3,6 - 4,5 a day raise...
7,54 x 7,54 means probably you are giving her 7,5 ml, 7 times a day... giving about 56 ml a day...
214 g / 30g=Oz, gives, 7 ounces, x8, so the demand is 56ml milk a day, the same number you got.
But she manage to take less. And this explain why she is increasing very slowly... Too slowly, really.
Yes, good question how to give more, when she dont manage to take more andhas even extended belly...
Gases, because of eating habits, and or burping? As Catwoman thought?
How was it, did you managed to get raw goat milk? This could help.
A memory arises. Once for at least 20 years ago, I heard about something against gases in the stomach... Some tried to use it on human babies, to stop colic... WHAT could it have been?
