Stranded on a Desert Island

If you were stranded on a desert island with your kid, what one item would you take with you?  Without a doubt, we'd take our ergo.  Is she tired of walking?  We can carry her for as far and long as needed.  Is she exhausted?  Nap time.  If it were lost or destroyed, we'd buy another one tomorrow...or possibly wait until babysteals had another deal on them.

I swear I do wear her, too, but I don't have all that many photographs of myself.  She's now nearly 3.5 and we're still going strong.
