I need advice on how to handle my DD's recent tantrums. They have started since I went away on a work trip. She had been waking up at 1am or 4am and screaming for and hour or more before we can persuade her to go to sleep using 'controlled crying'. She seems to be enraged, but I don't know why. She goes to bed like a little angel, and then wakes up screaming. I have just had a 1h30 episode this pm when she refused to take her nap. Am exhausted and no longer know how to handle this - please help!
