I know this question has probably been covered before, but I couldn't find it so...will she? She is 10 months old and some days I just hate hearing her cry - it goes for anything from 2mins to 20 mins every time she has a sleep. Do they grow out of it? If so when....(i realise as I write this that..of course they do grow out of it as I don't know many people who do this as adults )
