DS is 5 weeks and all he does is grunt. He tries to pass wind, he grunts. He tries to poo, he grunts. He feeds, he grunts. He sleeps, he grunts. Its the most god awful noise, like a wheezy baby elephant. Doc says normal behaviour and he'll grow out of it.....when?????!!!! He constantly strains for wind and pops loads and constantly wakes up from sleeps grunting. He's very difficult to wind after a bottle feed though. Does anyone else have or had this with their LO?'x
