DD2 has started shouting and screaming (not crying) all the time - around the house, in the supermarket etc.. She is a really happy baby and is not upset when she does this. She sometimes laughs afterwards! It is driving me mad. I have tried saying "No" in various voices and now trying to totally ignore it but she still continues. She is soo loud (literally ear-splitting) that I worry about her distubing the neighbours if the back door is open!
Has anyone experienced this and if so what did you do to stop it?
