My 15 month old DD was the angel baby who slept 12 hours and was so pleasant. Then about a week ago her attitude has suddenly changed and she cries at everything and wont go to bed. She is waking 3-4 times in the night and will not settle if i am not in the room. She can be fast asleep and as soon as i go to move she is awake and crying again. I am very tired at the moment and any ideas on how to handle things i would be grateful. If she goes for something and i say no she goes into a mad tantrum and lays on the floor screaming, this includes when we take her anywhere i am at a loss as to what to do next??
