I love the show ER!!! Sure it doesn't portray a "real" ER situation, but come on, it's just a show!!!!!! I still love it anyway, complete with Abby and her dysfunctional family: chuckle
I see no problem with a first grader seeing their dad in icu. Spending time with him is very important. I lost my dad last year. He was in icu and I was with him when he died. As long as the child isn't sick, I see no reason why not.
