8 week old stool

Just wondering if anybody's baby had any bowel movements that had a proper shape? My baby's last couple of poos have been a sausage shape but still soft. The GP and health visitor didn't offer much helpful advice so wondering if anybody knows. I can't find a single thing online so it's baffling me! All I know is they shopping really have a shape until she starts solids. No idea why they have a shape? 😅
