Re: failing at parenthood??
I was in a very similar situation Motus. Hugs to you and your little one.
Take her to the doc and insist that she be evaluated for reflux. My firstborn they never really evaluated because he didnt have the “textbook” symptoms of it so he went 2 years without treatment due to inept docs. Babies do not need to be uncomfortable. She likely has reflux, likely needs medication like zantac for it and will very likely outgrow it by age 1.
Dont suffer. If need be, take her to an emergency room and insist on treatment. You wont regret being pushy about this once you see the results.
Other things that help - use a bouncy seat with a vibration setting. Let her sleep upright by putting blankets or pillows under the head of the mattress. Warm towel on tummy and tummy rubs.
I wish you the very best and please let us know how things go…
