We had Käthe x-rayed this afternoon. Ten! Ten skulls he counted in there (though is looks like 20 spines!). She's been widening quickly this week, and added 20 pounds since the sonogram. We see why.
Understandably, Käthe is uncomfortable and likely as ready as anyone for these creatures to get out of her. Due date is Thursday, and I think it'll be a marathon for all of us. Wish her an easy and healthy experience.
