Hi. I don't know if anyone has had or is experiencing the same problem as me at the moment, but my 2 year old son has started ferociously head banging in his cot at night/to get himself off to sleep. Everyone keeps telling me it's normal and he'll grow out of it and won't do himself any harm but i'm really worried as it's so loud and can't be doing him any good. He does it more some nights than others but doesn't seem to be related to how tired he is/what we've done in the day etc etc.
