Experienced mamas

Okay so my 9 day old daughter is in a ton of pain when trying to poop . It's the worst at night and I don't know what to do . I comfort her as long as I can but when I feel like I'm ready to fall asleep I have to put her down and she gets back to getting upset and try really hard to poop. She's a breastfed baby and she isn't constipated . Her poop is still soft and runny . I don't know what to do to relieve her cus the bicycle legs haven't seemed to help yet . Any advice or recommendations that have worked for your little ones ? TIA
