As with all babies, they have to move from the bassinet to the crib. It's no different for puppies -- they have to move from the piddle-pad-protected kitchen to their very own crates. Because they are siblings, we understand they have to learn to be individuals to avoid various monster-like traits (read: Bella!); part of that training is done by providing them with their own beds.
Last Friday night, we decided it was time for operation crate sleeping. It went remarkably well, considering it was their first time sleeping alone without the other's belly to cuddle up to (yes, it's okay to whimper at the thought). To mark such a momentous occasion, we shot a short video of their initial reaction to the crates.
I was up until 1am making sure they had water to drink and then the associated potty break in the back yard (yes, I wore my pajamas out there). I was so tired at one point, I almost justified sleeping on the dog bed with my arms around Baxter.
The nights since have been much better. Sure they still get up in the early morning (4am-ish), but they seem to be understanding that this is what happens. Another right of passage, I suppose.
