To Melatonin or to Not Melatonin That is the Question

It is past ten pm. I can hear LB upstairs in his bed playing with toys, which is a slight change from coming downstairs every five minutes. Weve been doing this dance since seven thirty pm tonight. We do it nearly every night. He and LS are always staying up amd tryimg to play even though they are in seperate rooms. LS is finally asleep, but LB hes still goimg strong. Im now taking the ignore him approach. Hoping he will soon sleep. The only nights he doesnt do this are the nights I give him melatonin thirty minutes before bedtime. And even then sometimes that doesnt work. There are no clear studies or facts about what long term melatonin use does to kids. So I try to not use it very often. It is a natural supplement but even those can have long term effects if used for long periods. I want him to have a regular sleep schedule and get enough sleep without the melatonin. we have a strict bedtime routine and time and I do my best to make sure all three kiddos get a lot of energy running out time during the day when weather permits. Like today we walked to the church and played with BB’s new stomp rocket in the very large field like yard, played on the play structure and then walked home. BB as usual was out like a light about ten min after getting in bed. I wish I knew why the other two have tis need to fight bedtime so hard. Do any of you other parents out there use melatonin for your kiddos? have you found anything more than I have about its effects? If anyone has any ideas or any info please let me know!
