Hi, I have a 2yr old CAH salt losing daughter who is quite advanced verbally and socially and is extremely independent.Problem is that her moods fluctuate from extreme highs, she buzzes around everywhere, won't eat or sleep and you just can't slow her down, then she slows down sometimes becoming quite teary at nothing. She is hyper, almost hysterical in a way for days on end then comes back to normal for a couple of days then it starts again. Has anybody else experienced this, or is it just the "terrible two's"?
