I'm a little dense when it comes to forums. I didn't realize that your "Attorney" comment was sarcasm until I saw your second post. lol. I was like "Is this guy/lady out of their mind!!!?" LOL.
Op, I understand that sometimes we can get a bit overprotective when it comes to our children. But, let's think for a minute. Why would a Nurse intentionally endanger your child? Even with the moral issue aside, why would s/he jeopardize her job like that? Please don't go to the BON over this. She was likely just being friendly to your child. Is there something that you maybe left out of your post? I'm wondering what those "Other things" were that the nurse did that you were uncomfortable with... It IS possible that one of those other things may have been inappropriate, I dont know, but the incident described in your post (unless some info was left out that may change this) seems harmless.
Again Ma'am, PLEASE don't pursue this with the BON.
