Melatonin helping Mood

I just wanted to update on what is currently helping Caleb. We've struggled a bit again with mood...a bit of "screaminess" and the "no" answer for everything. One evening I went upstairs to give Caleb a mb12 shot, hoping it would again bring about a period of good moods. However, I wasn't able to give it because Caleb wasn't asleep...even at 10:30 pm. I decided to give some Melatonin the next evening because I know that he is a kid who NEEDS sleep! Low and behold, I noticed a much better mood the next morning. Whether it was the melatonin, or the increased sleep, I don't know. But...it brought about the desired mood increase :)
