S.S.
I am not sure why you would feel that a 5 year old would be a threat to your son. If this little boy is in a home where it is totally disfunctional it is only natural for him to seek out somewhere he feels safe. You are only 32 so you may not know the term "kool aid house" but anyone over 40 will. Make your house the kool aid house in the neighbor hood and you will always know right from the start what is going on in your childrens life. If all the kids feel safe and ok playing at your house then when they are older they will be in "your" backyard swinging and your drive way playing basketball and in front of your house skateboarding. they will be ok with playing board games at your house cause your the cool house. Their friends will be ok with hanging at your house becuase your the cool mom. Make it accessable now. Don't wait until they are 14 and looking for somewhere to get away like this kid is doing at 5. i grew up in the koolaid house. My mom never turned friends away. Consequently I have a houseful of kids all the time even though my kids are at college now. When they are home their friends have no problem hanging out here. It is work when they are smaller. but the blessings are tenfold. When I was going thru cancer treatments christmas before last I had 6 teenagers who spent new years eve with us playing games and then just talking as I fell in and out of sleep. these children who have been in my kids lives call me for no other reason than just to check in even though they are not really "my kids" A really nice teenager is nice for a reason and it usually is becuase of an adult they come in contact with while they are young. I hope you are able to see past the parents problems and don't cause this little one any more hurt than he may already be getting at home.
