Our DD10 (ADHD inattentive type) has always had the worst time falling asleep. Her brain just whirrs and whirrs. She is miserable unless allowed to read or draw - which she does for hours and hours. That sounds ok but the reality is that during school session she would not get enough sleep. So, the doctor recommended melatonin, and it works like magic. However, if one reads about melatonin, there are all kinds of warnings about the danger of melatonin usage and puberty issues. The warnings are never specific so I dug deeper and saw that it may delay puberty (studies of rats and such). What information have you all found? Is it something I should be concerned with, or do I decide that a good night's rest outweighs the danger of the small amount she takes at night (I quarter a 5 mg tablet so tiny tiny amount).
