DS5 is on heavy dose of Melatonin and Hydroxyzine to top it off (helps with his allergies while it relaxes him). But there are many nights when even that doesn't help. The last two nights though (first two days of Kidnergarten), he's aout 30 minutes after I'd give him the meds! smile ... BUT he keeps waking up through the night about every 30 minutes. I think the excitement and craziness of first school days is keeping him too hyper even in his sleep.
