Thank you for your answers.
I have elected to get the Cobra benefit for him, I had just 2 days left to elect it!!!
I kept praying for guidance and I really feel that this was answered with just 2 days left to deciden. His bio dad said he would help, keep fingers crossed on that he has been known to back out of stuff.
So I feel at least 4 months coverage should do this, it is expensive, but I don't think there are any alternatives. I'm still going to put him on the waiting list for the state insurance. At least he'll have something later down the road.
why don't kids realize how important it is to make sure you get a good education, find a decent job that has good benefits! They don't understand how important this stuff is.
