Can I babysit overnight in the following situation?
There is a 16yr old girl, 15 yr old boy, 12 yr old girl, 8 yr old girl, 6 yr old girl, and 2 yr old boy.
It is not considered yichud, because there are four girls here, and theyt are the boy’s sisters. Therefore even though it is at night , it isn’t considered yichud.
