Quoting Mama Mallo (::" I give my 2.5 year old melantonin almost every night. Otherwise he only sleeps like 4 hours a night. I'd rather him get a full nights sleep! I only give him 1/4 of the pill though!"
Did a doctor recommend it or was it something you heard was safe?
I could probably call is pedi and ask although, she is really into natural medicine over western medicine(though she is an MD) so I am sure she would say its safe. I am just paranoid I guess XD
Your son sleeps well on it though? :]
