Anyone’s baby has clay like poop? (Consistency )

She’s straining a little and doesn’t cry but it comes out with the texture of clay and a lot! She goes every 4-5 days ... I told the dr he said give her oz or 2 of water or oz of prune juice with oz of water . She is strictly formula fed I’m not understanding why her bowel movement would change .
