My son is 5 weeks old today. He wakes up about 3am - 4am to eat and then from then on grunts so loud in his sleep that my husband and I are awake. We swaddle him and he just grunts like he is uncomfortable non-stop. I have tried not swaddling, but that doesn’t help. He has reflux and is on Zantac, so he sleeps propped up in his bassinet. Any suggestions? I am getting no sleep and need help!
