remedy for child that cant fall asleep

My son seems to gave a hard time going to bed at night. He seems to always be freeked out about something in his room or finds some reason not to go to bed. Is there something I can maybe give him to help him fall asleep?? And he doesn’t get a full nights sleep like he’s supposed to.

I use to get my boys all ready for bed and then we would get the box of sleep time tea out. Make the cup and they would drink while they watched a bed time show. They love the tea but the suggestion of it making them sleepy worked. We went shopping and bought together and I explained to them that it helps relax for bed. Funny thing when they are feeling sick now they still ask for it. Hope it works for your little one. Amazing the power if suggestion!!!
