Hmm. My boy poops everyday as well, 1x per day but a lot. There was once he poops twice in a day, and didn't poop the next day. (Maybe because he already poop twice the previous day) And then the following day, he poops again. If baby is not passing hard stools, I guess should be fine? But do monitor for stomach discomfort etc.
It might be tummy has wind, stomach discomfort or too bloated. Just ensure next day baby poop otherwise visit doctor to seek advice. Meanwhile continue to massage baby tummy and do bicycle exercise during massage for baby to ease the stomach discomfort
