Grunting and Groaning is NOT normal for newborns
It's definitely NOT normal. Although babies outgrow it, they are in an enormous amount of distress while it is actually happening. I refused to accept my MW dismissing it as 'oh some babies just like to hear the sound of their own voices.' I started him off on dill seed as a brew to help ease the wind build up ( it's the active ingredient in gripe water minus all the alcohol etc). This helped a bit. I then booked him with an osteopath. The treatment worked instantly! The osteopath explained that the stress and pressures that the baby goes through during childbirth is so intense that it causes an enormous amount of strain on the head and upper chest. The grunting is symptomatic of this.
