We have been there, it’s heartbreaking and exhausting to everyone. Pd gave us Bifibaby probiotic and Ridwind. We added into her fm on different feedings. My husband carried her in his arms and did deep squats to calm her down, sometimes she would fall asleep. Then we got her a yaolan (baby hammock) and that seems to be quite helpful. It a phase and it will pass. Hang in there.
I gave bb ridwind on alternate feedings and use digestive balm from inaara organics after every diaper change. It’ll slowly get better!
