Lucas has always been a horrible sleeper but for the past three months he has been getting 6 hrs of sleep a day...3-4 hrs at night and then a 2-3 hr during the day. I even tried cutting the nap out and he would only sleep 2-3 hrs then and just be up. Couple nights ago I finally needed a good night sleep so I gave him melatonin getting permission from his ped. He slept amaZing! Fell asleep at a good time and woke up at a decent time and even took an hour nap. And the moment I didn’t give it to him he back to only sleeping 2-3 hrs at night...he has an appointment next week but Anyone else have this issue?
