How long has he been on the new medication? Hopefully, his body is simply adjusting to the new levels. When we first found out Christina had CAH and started the cortisol, 'moody' was a nice way to describe her days. She had just turned 4 and would cry and cry....and she would even say to me, "I'm crying and I don't know why....I just can't stop crying". That went on for a couple weeks. Every now and then, she'll have episodes where her hormones get the best of her...and she'll become weepy and sulky. Keep track of it and make sure you tell his endocrinologist if it doesn't seem right to you.
