Baby struggling to poop or pass gas in the early mornings

Hi mamas! My LO has been struggling to poop or pass gas every time after the early morning feeds (BF at 5am ish) and always grunting, eventually doesn’t sleep and cry herself awake. This straining and grunting won’t stop until she cries herself awake and I feed her again and that induces a huge poop in the morning. Is this normal? How do I help her sleep better? I have tried tummy massage and leg cycling methods to pass gas but it doesn’t help!
