From Space to a Tall Mountain

Dear Ellie,

It's official, you've been upgraded to a crib.  It's odd, not seeing you inside of that airtight acrylic dome.  The crib looks so... low tech.  I remember in my first few letters I compared you inside of the isolette to a person in a space suite.  How you couldn't survive long outside of it.  But now, in your crib, you look autonomous.  Able to survive on your own.  Now that I think about it, that's very close to being true.  If we took you off of the oxygen, its not impossible that you could still manage to breath entirely on your own.  You might suck in air like crazy and struggle a bit, but you would surely last for a few minutes or even hours without turning blue.  Instead of being out in space, you'd be on top of a tall mountain, instead.
