Help trouble shoot a feeding problem

DD gets one bottle of breast milk before bed at 8pm. DH gives it to her because it's his bonding opportunity with her. For 8w DH would wrap her in the miracle blanket, give her a bottle, and then she would sleep for 6 hours.
At 8w we started putting vit D in her bottle per pediatrician request to get vit D. About 5 days later bottle time with DH was a disaster and has not been the same since. She cries and cries. Some nights she is very gassy, some nights just fussy. We tried stopping the vit D in the bottle, changing her position while feeding, I bottle fed her for a few nights to see if it was just DH, we used fresh milk instead of refrigerated milk, went up to the 3 month nipple, and tonight tried to remove the blanket during feedings. If after a few days that doesn't improve, my next thought is to try a new kind of bottle and then I am out of ideas and I might just breastfeed her.

For a little bit I thought it might be behavioral, but now I don't think it is. She is legitimately starving. She starts to suck vigorously and then within 30 seconds she pulls off and cries a painful cry. When she arches her back it is usually gas, but after several big burps/farts she will suck vigorously again and about 10-15 seconds later she tantrums and the cycle goes on until she just falls asleep. Sometimes she just kicks her feet and tantrums and then when we remove the bottle, she sucks on DH shirt (signifying she is hungry). Because she isn't feeding as well, she only sleeps for 2-3 hours and then wakes up to feed.

Thoughts anyone? Is it common for a baby to like a bottle for 8w and then all of a sudden not like that bottle anymore and need a different kind?

Have you tried increasing the bottle and putting gas drops in the bottle?

Re: Help trouble shoot a feeding problem

Our DD has very bad gas and it sounds like yours might also. Try gas drops or gripe water, try bicycle legs also. It's so hard bc sometimes you just need to wait for it to pass. There wasn't a bottle that helped either and we tried everything. I Hope it gets better!

Try putting gas drops in her bottle. Could just be a phase
