Hope you arent going too insane!
Are you still giving her solids hun? what times and how often? have you changed how often she is being fed at all? Charlottes sleep often gets erratic when we change her meal times or something.
Perhaps worth having a look a any new foods you have introduced in the last week or so to see if they are affecting her.
Taking her for a walk is definately a great idea, or the car is usually a winner for us.

Oh, is she teething?
Good luck! I hope she comes good soon
