My best guess, given her behavior (wake up hollering, refuse all comfort from daddy with howls escalating, soothe almost instantly with momma and go right back to sleep) is that she's probably having nightmares. I wonder what toddlers have nightmares about. Mommy disappearing? It could also be teething pain, but I don't think that would soothe so quickly. She's also not been sleeping great during the day, which may be contributing to it -- apparently if they're underslept on naps, that actually contributes to worse sleep at night. Frustrating. It might just be a growth spurt too, in which case we try to ride it out.
But Kavi's fine now (trying to feed her dolly with the bottle of milk she just finished, insanely cute -- she also likes to have all her stuffed toys kiss each other, and it's hard not to crack up when the yellow monkey is kissing the huge stuffed bunny), so I'm going to go snuggle with baby and watch Bob the Builder.
Can we get through this? Yes we can!
(That would be funnier if you actually watched Bob the Builder. :-)
