Advice?

I really need to sit down and update the blog - so much has been happening lately, so there's a ton to write about, but not much time.  Maybe tomorrow :)

I'll give you this one glimpse into our crazy life:

G & L now are able to climb out of their cribs.  Mercy.  This is what I found yesterday when I went to get them up from their nap.  (It's amazing how quickly they can trash a room!)  Then this morning, Gus had climbed out, raided his dresser and had piled up clothes beside Lula's crib as a landing pad so she could climb down.  (I'm assuming here.)
The thought of them falling out of their cribs horrifies me (especially if Lula has a recurrence of ITP).  Any advice for keeping them safe and contained?  Besides cages, obviously :)
