My sons doctor said we can use melatonin, is she right?

How old is he?

In moderation. I do on occasion for my little one who's 2. If possible, try getting him to cut that late nap out. I think thats the issue.

So I used it with my daughter when she had night terrors and needed a better sleep schedule. This is what her pediatrician advised for us. We were to use only for 2 weeks to help create her natural sleep cycle. We would give it 30 minutes prior to bedtime. Also we created the same routine each night, from set dinner to getting ready for bed. After the 2 weeks, we could give it every other day and wean off as the pediatrician wanted her body to create its own melatonin as her body should have established a better schedule, while still maintaining our daily schedule. We used the olly melatonin gummies. I recommend making sure to brush teeth before bed to prevent cavities.

Now my kids use the olly chillax, which is the magnesium and they sleep good with that. They are restless at night

I think you need to be sure not to do it for extended periods of time, like any other supplement it is not meant as a long term use solution. I'd be sure his iron is good and rule out any other health issues that are contributing to it as well. Definitely use for short term as you work through long term solutions. Good luck!

We used it last year when our daughter went through a horrible sleep regression/sleepless phase. We tried everything to the point that I took her to a neurologist because we were at wits end. She gave us a sleep hygiene schedule. She told us to try it for three weeks and if there was no change, we could introduce melatonin (for a maximum of 3 months if absolutely necessary). I used the melatonin to create the sleep schedule. I cried that first morning she slept through the night. We used it for a month I think. It was a godsend for us. My daughter was 19 months at the time. She’s 2.8 yrs now.
