Kendamil comfort vs Hipp HA pre??

Kendamil comfort or hipp HA? My 7 weeker is currently combo feed with kendamil goat sunce day 1.. Her main symptom is gassy that she farts and trying to pass gas all day and night. It bothers her so much that she would arch her back, red face and cry. Fussy and unhappy. She also has baby acne, cradle cap, some mucus stool and congested. Currently, it’s hard to feed her more than 1oz without her refusing it. She barely drink either breast milk or formula. Still gain weight but we are exhausted from her crying all day and not sleep well at night. Granted she has never been good sleeper since birth
