no electricity help me with these questions.

Electricity is not a neccessity as long as there is food heat and hot water available I don't think there is cause for concern. These kids will have the benefit of using their imaginations for entertainment, rather that watching television or playing video games. Not a big deal. I raised my boys for a while in nothing but the shell of a trailer. We had no electricity, and no running water in the house. We had a wood stove for heat, and water came from a spicket out side and was heated on a fire outside, food was cooked there too. In all of my oldest child's memories, he cherished that one. He told me that he learned a lot about survival during that time, and he was only 3 or 4 at that time.

If the children are well fed, have heat and hot water to bathe then I don't see the problem. I don't think lights fall into the category of needed to survive
