Waiting for a Thud

I'm sitting downstairs in my family room waiting to hear a big THUD from above me...

Ethan has outgrown his bed, so we moved in a "big kid" bed we purchased at a garage sale this summer. It has legs ("Hey, I can put stuff under my bed!") and includes a box-spring and mattress. As a result it is about 2.5 times taller than his previous bed.

The problem lies with the fact that Ethan has a tendency to fall out of his bed about once a week. Sometimes he doesn't even wake up; we find him lying there on the floor with one leg still up on the bed. He'll definitely wake up if he falls out of this bed!

On a side note, I have one more coat of white paint to put on Ethan's old bed before we move it into Morgan's room tomorrow night. This is her last night in her crib!!!
