The most effective way to exercise for fat loss is to create a program that combines high-intensity and low-intensity exercise. Thatâs because each type of exercise promotes fat loss in different and complementary ways.
Since you asked, I do think it is odd that your grandchildren sleep with you if you have other accommodation available for them. Also, a nine-year-old should be able to bathe or shower alone. I would worry more about lack of independence at that age than anything improper, but at age 9 I would expect a boy to be more modest than you are describing.
Children above that age can be left alone for a couple of hours and we look at the maturity level of the children up to 12 years of age. There is no law in KY that addresses this issue. Don't leave young kids alone in Kentucky. A child should not be left home alone in Kentucky until they are 11 years of age. There is no law per se, but I work in the child welfare arena and if your child is younger than this and being left alone child protective services will take a report and investigate a child left alone younger than 11.
