Can I visit them? (Redux)

Yes, you can visit them.  You don't need an engraved invitation.

However, since Ginger's been released from the hospital, we're no longer there 24/7, so it will be necessary for you to coordinate your visit with us to make sure it occurs when one of us is there.  The NICU requires us to put your name on a list of permitted visitors or to be present with the visitor.  As I mentioned before, our bedside visitor maximum is four at any given moment (although there is a waiting area nearby and we can let an entire tour group in, if we do it in four-person shifts).  Sadly, kids other than siblings are not allowed.  While you can touch them, the NICU recommends that only moms and dads hold them at this point.

If you're planning a visit, call one of our cell phones or send an e-mail to my Gmail address for the most up-to-date information about when we'll be there.

Last suggestion:  Wear short sleeves, and be prepared to remove any jewelry worn below the elbow, because you'll be required to scrub up.
