Crying

My LO is 2 weeks old.While in the hospital i breastfed & bottle fed (similiac pro advanced)She had no issues.Once i got home i was still doing the same but it seemed as if she started having issues.Every time she poops she screams bloody murder. I went to the pediatrician he gave us Gerber soothe.Now that she’s on that i see no change.The poop is soft. After she finishes she’s back to normal. I spoke to the pediatrician he said unfortunately some babies do that & it should pass with time..Anyone else experience a screaming baby😩Like to the top of their lungs
