I have a seven year old second grader who told me his mother and father both work at night. He says his 11 year old sister takes care of him while his parents work. He had specific details like they heat up a pizza for supper. The mother calls them and tells them it is time for bed. He had a burn mark on his arm and said they(he and sister) tried to cook french fries. We had conferences this week and I asked the parents about their work schedule and dad said that he works at night but the mother doesn't. I mentioned to them that I was glad to hear that because a seven year old shouldn't be left at home with an eleven year old. They both agreed but left in a hurry. My question is: Should I leave this alone or do some more investigating. Should I call social services and let them do some investigating? I don't want to start something if there is nothing to start. However if something happened to this little boy and I knew he was alone and didn't do something I could be held reliable. What would you do? Is an eleven year old capable of caring for a seven year old? Why would this little boy make this up if it isn't true?
