Breastfeed babies hard to poop

Is it normal for a breastfeed baby not to poop regularly? My baby's one month already and it's been a week and 2 days since her last bowel movements she just always pee, fart and burp, her tummy is soft everytime I have to check on her. #pregnancy #firstbaby #1stimemom #advicepls #theasianparentph
