sleep time requirement for my child

A. 8 to 10 hours minimum mark good for every child and even for an adult or minimum eight hours is good for a child it can be 8 to 10 hours as the growing age only they live for this much time with our progressing age of studies just get 7 to 8 hours in a night but if you can manage for 8 to 10 hours every night in total then that would be very good
