Forgot to mention the other day her sister got her in the back of the head with a toy which in turn gave her a blood nose, we went to emergency as i found it odd and she didn't seem herself, she was hell that night which we put down to a headache, the next day was her b'day she had 1 day sleep and a big day and actually went off quiet easily at her nans then yesterday she was feral again.

I just went in to settle her then, the minute i pick her up she is basically asleep on my shoulder, i sat and cuddled her, tried putting her into bed 3 times.. SCREAMING.. i fed her she was asleep even enough for me to remove my boob which is normally my cue to put her in bed NOPE she's crying again.
I am leaving her for a minute and will see what she does, might have to feed her to sleep on her sister little couch or something...

I have no idea whats wrong with her... should i be worried about the knock from the other day?
