For kids who are so hyper and stay up very late at night, would you recommend Mosegor to help them have a good night sleep? What other alternatives can you suggest?

Maybe u can try bringing them out after dinner, jus take a walk in the mall or park. Make them walk, climb the stairs, so by the time they reach home, they will be quite tired. Then do calming down activity eg shower, story time, dim the lights. It really depends the day activity and whether nap is taken and how long, tat will affect night sleep. My son used to have light activity in the day, then his nap is like 3 hours in the afternoon, at night is very hard to get him to sleep. Once i let him have outdoor activities and shorten the nap n get him to bed early, even though he will talk and talk non stop and wan books after books, he will sleep by 9.30, 10
