My five week old little boy makes noises at night and I need help knowing if they are feeding cues or not. He opens his eyes, makes relatively quiet but unhappy-sounding grunts, waves his arms around (if his swaddling has come loose), makes ugly faces like he's about to scream, then goes quickly back to sleep. He does this often all night and my husband thinks he's just doing it in his sleep and that it doesn't mean anything. I wonder if he's hungry and I need to feed him. I've been feeding him every hour and a half to two hours at night but a lot of times we have to keep him awake to feed long enough and honestly, it's driving us crazy. Two nights ago my husband convinced me to put the baby in his room and set the volume on our monitor to a setting that lets us sleep through the grunts but hear actual cries. We slept almost 5 hours straight both nights! I'm wondering if this is ignoring my son's subtle hunger signs or if I should thank my lucky stars that I can finally sleep that long. My parents say, "Don't worry - he'll make sure you know when he's hungry! If he's not waking you up crying, he's fine." Any thoughts?
