Gas drops or gripe water! A lot of bicycle and burping. Unfortunately, up until about 3 months this is completely normal for babies. Both of mine were colicky. By 4-6 months, you'll be out of the trenches. I know it's hard, but try not to stress about it too much. Do what you can to help while giving yourself grace knowing by accepting that this is a temporary reality for almost all babies and your LO is almost out of this phase. When babes is a tad older, try sitting them upright to help poopies come down. You can also add proviotics like BioGaia.
Be patient, sometimes this will help sometimes not. It’s just a phase
I experienced it with both kids, but longer with my second. Is baby formula fed or breastfed?
Be patient is normal, I went through that with my daughter.
