Well have you dicussed this with them? Let them know how you feel about it and what's been going on.

That would be great, but how? I would like to stay friends.
They havent even called to ask how he is. How would I start?
His face looks bad. I called him off school and stayed up last night
watching over him. My husband would say I wouldn't let him do anything if
it would keep him from getting hurt.
I know his a boy and is going to get hurt, but I think as his parent I should
protect him from getting hurt as much as I can.
Thank you for your help, I will try to see there side.

Well first you should want to meet up with them face to face. Over the phone ughh I wouldn't do that. Tell you want to discuss what you would expect from them while watching your child. If they can't comply with that you shouldn't let you child stay with them. How old is you little boy? I don't have any children so I'm trying to explain to you from what I think I would do.

hmmm Maybe just let those kids come over to your house... but try and avoid letting your son going over.... unless he really wants to... If he does want to then you will have to speak to the parents face to face about it. If he doesnt enjoy himself over there then he shouldnt go over there at all...

If his face is so bad you watched over him like that, why haven't you taken him to the hospital?

Did he run right home after getting hurt and didn't let them care for him?
Do they know he got hurt or how severely he was hurt?
Have they seen him since the accident?

Maybe they are simply embarrassed and upset that he's hurt and feel bad for it happening.

Other questions:
Do you watch over the children when they are at your place?
Do your friends watch over the children when they are at their place?

In otherwords, are you being responsible and they are not?

Do you have comparable toys/activities to this inter-tube connected to a four-wheeler at your house? In otherwords, are the activities available at this other house more dangerous than the activities offered at your own?

It seems that your friends' house is a more accident-prone environment compared to your own, whether because of a lack of supervision or because more dangerous activities are done at their house. You're going to have to decide if you're okay with that or not.

If your friends are used to these types of injuries they may not think of it as anything to get worked up about. If you're not used to these kinds of injuries, then it makes sense that you'll be more worried. I'm not saying either way is better; that's just how it is.

Thanks for all your awnsers its helped. Im glad to say his face has healed nicely.
He wants to go play there, we have said his not allowed to go with out one of us.
I worrie alot about my son his a momma's boy, and my only child. I know kids get hurt, I just hate to see my baby hurt or sick.
Kids are well looked after at my home. I just say the more risk the activities the more the child should be watched.
I will keep my friends there nice people, and I love there kids as if they were family. I just want them to treat my child as I treat theirs.
Thank you all.
