Melatonin dose for 3 year old?

[Guest guest]

Hi all -

We are considering starting our 3 year old son on melatonin to help him sleep,

both at naptime and bedtime. He just turned 3 and weighs a little over 30 lbs. I

was wondering what the appropriate starting dose would be for a little guy? Do

you give it at naptime also, or just bedtime? He has a quiet time every

afternoon, but he rarely sleeps during it, even when utterly exhausted. At

bedtime, no matter how tired he is, he gets back out of bed and plays after we

put him to bed. We really want to see him start to get the rest he needs,

especially now that school has started for him.

Thanks!

Bridget
