DD is 6m, generally very smiley happy baby, breast fed on demand, sleeps well, but just recently she makes this horrendous groaning noise, for like an hour at a time, in the evenings. It is driving me insane, it's SO LOUD and nothing seems to stop her!
I have fed her, changed her, played with her, and she still does it :( any tips? It really really hurts my head and my patience is starting to fray, don't want to shout at her for something she can't help.
