She is 20 weeks old.
I had one like that, whatever I did she grizzled about it. She had colic but also seemed to just be generally unhappy. Even though it's really frustrating there's not a lot you can do, I had mine in a sling and even though it didn't stop her grizzling I thought that it was best for her to still be held and be close to me so that she was aware of my being there.
I even took her to an osteopath to see if it could help and while she was a lot calmer afterwards (apparently her diaphragm had been squashed during birth, she was born very quickly) it didn't stop straight away.
Mine learned to shriek and yell at that age and hasn't stopped since. Its in fun.
Does your babe seem in pain, or is it just the noise bothering you?
