There is a book that has worked with every sleeping problem my daughter (and my sister's son and daughter) has ever had. It's called "healthy sleep habits, healthy child". Also, my daughter went through the same thing (a couple times) and we had to do the cry it out/behavior extinction, and although it was HELL for a week, now she sleeps from 8pm to 9am. (HEAVEN!!) I realize that alot of moms hate the cry it out idea, I felt like the worst person in the world. I had to focus on the fact that if I wake up seven times a night, I am way too exhausted to be the mom I want to be during the day. And by teaching my daughter that crying/screaming/temper tantrums don't work to get what she wants, her behavior is better during the day also. (and she isn't as crabby, because she is getting the sleep she needs at night) Also, it is a good idea for the child to be tested for diabetes. There are more ovbious signs of childhood diabetes, the most important is the failure to thrive (weight loss, poor health).
