Well, I'm not discrediting what you say could be the cause for your BIL's actions..... it's just when my oldest son was born he had the cord wrapped around his neck three times-- (the doctors said)-- he was totally purple when he was first born and had to be given oxygen-- it was a very scary time. (the doctors were very concerned about his well being) He's in college now and is honest and very driven in "playing by the rules"-- high moral standards.... he gets straight A's but does have some issues with self-injury and high expectations of himself and is very very neat and orderly.
So I don't know if the cord thing has anything to do with your BIL's actions... but who knows??? just thought I'd share my experience so you could maybe compare.....
Oh yea, and WELCOME!!
