Help, grunting all the time

Cynthia

My LO is 4 weeks. Since he was 2 weeks he’s been grunting all the time. His dr said it’s normal and that he’s grow out of it. She suggested gripe water, mylicon, swaddling and a pacifier. We’ve tried all of this and nothing helped. We are exhausted, especially during the night. Does anyone have any other tricks/old wives tales? We’re desperate!
