Another good job, VT. I've been skittish about 4e, so I'm glad to see you're still using 3.5 format for your monsters. Undead toddlers are always good for a "WHAT THE FLYING F-" moment. ("No, it's not flying, it's an undead lifesucking baby.")
I'll admit, I too was thrown a little by the low CR for a creature with high hit dice and powerful attacks, but it looks like you thought about that already.
