The saga of Baby Bird Balloon

Once upon a time, Xander went to Yasha's birthday party.  At that party, there was a goody bag.  In that goody bag, there was a white balloon.

When Xander got home, Mommy blew up the white balloon.  It became big and round and full of air.  When Daddy took the end of the balloon and moved it in and out, it squeaked.  Xander said it sounded like a baby bird.

White Balloon therefore became Baby Bird Balloon.

Baby Bird Balloon squeaked and squeaked. He asked to fly.  We let go of Baby Bird Balloon and whoosh! Baby Bird Balloon flew all over the room.  Xander loved Baby Bird Balloon flying.  He flew, was blown up with air again, and flew again.  We did this many, many times.  Many. Many. Times.

Then Xander encouraged Mommy to blow up Baby Bird Balloon even bigger.  "Bigger, Mommy, bigger!  Make him a Big Squeaky Bird!"

Mommy blew up Baby Bird so much that he popped.  Baby Bird Balloon became Baby Bird Burst Balloon Bits.

Xander cried.

Mommy said she couldn't fix Baby Bird Balloon.  But she rolled all the bits together and together and over and over in themselves, until Baby Bird Balloon was a thimble-size bundle of latex.

Baby Bird Balloon thus became Baby Bird Egg.

Baby Bird Egg slept with Xander last night.  Baby Bird Egg had breakfast with Xander this morning.  Baby Bird Egg, according to Xander, will hatch soon.
