Cribbed

Our new baby is a little crazy.  By this I mean that she is not at all like her older brother: not very cuddly, not very mellow, and very high energy.  This is not a problem exactly, but it has led us to a weird problem I don't know how to solve.  Every night we put her down in her crib (around 715pm, a complete victory, thanks very much), and she goes to sleep pretty easily.  But... she thrashes around constantly, and wakes herself up a couple times a night by getting her legs caught in the crib slats.  When this happens she shrieks like she's a missionary being prepared for the pot, and we run in to save her from the hungry cannibals.  Sometimes this is not so easy, as little crazy has inherited her parents' thighs, and she wedges these chunky members pretty tightly between the slats.  So what do we do?  We removed the crib bumper when she started to move around, because she once stuck her head between the crib wall and the bumper.  I can't think of what else I can do to protect her legs and feet from the slats without endangering her with something she'll pull off and stick into her mouth.  Do I set up a hammock and ditch the crib?  That sounds like a recipe for disaster when she figures out how to roll out of it.  Do we ditch the crib and put her on the floor?  Buy a dog crate?  

Clearly, I have not one single practical idea.  Do you?
