Funny, DD sleeps so much better with the melatonin and she wakes up dry most mornings after having the pills. I usually just give it to her at bedtime and she seems to fall asleep fairly quickly (compared to before which isn't saying much

) I would say she is asleep within a half hour of taking her pills. We give her 2 most nights.
without the pills she was awake quite a bit and she wet the bed. we woke up to a soaking wet pull up everyday! she is almost 10.
