I think I would push, too. I am glad you asked this question. Our son has avoided the hospital for a year now, but prior to that he was going in about every 2 months and he has terrible veins. Iv's would not last more than one day and sometimes they could not even get a PICC line. I was determined to ask about the port at his next hospitalization, but was not sure if they would do it in a child so young. I was glad to read the other replies to know that his age should not be an issue. It is a horrible experience to watch him go through and the older he gets the more he understands and the more he fights that kind of stuff. I say fight the good fight, too. There is no need for her to continue to have to go through that. (I may need reminded I said this when I am having the same fight and tempted just to give into the dr.)
