Baby cries when he is having BM

Ka

Ladies,

I have a 4 week old baby who screams every time he is having a bowel movement. He seems like he is in so much pain. He starts peddling his legs, clinching his fist and cries. Has anyone else had this problem? I’ve tried Gerber Gentle Soothe Colic drops and Little Remedies Gas Drops. Unfortunately, these do not seem to help. He’s not constipated because he has a BM after I breastfeed him. His BM are mushy like they are supposed to be.
