My 3 year old daughter has night terrors, night sweats, and is extremely moody. If you tell her no, sometimes she's fine with it...or sometimes she'll start whining and throwing a fit like a normal 3 year old...but there are OTHER times when she flat out tantrums like she's out of control. Her behavior is very similar to the behavior in her night terrors - shaking, seeming like she's somewhere else, screaming/crying, etc. At these times, it "feels" like it's chemical and she has no control over it. I've read online that tantrums like these and night terrors are sometimes linked to bipolar. But, she's so young, I'm afraid I won't find a doctor who would take it seriously with her age. Thoughts?
