Helppp

My little guy (7 weeks) sleeps great during the day, no grunting, arching or discomfort and naps long stretches; but at night he is still waking every hour or every 2 hours so uncomfortable like he’s trying to pass gas or poop. He does nap in swing so he’s inclined, but sleeps flat at night. Could that be why? He has appointment this week so I will talk to doctor.
