This is my own damned fault. I slept in and then when I woke up, I wanted to have breakfast before naptime even though there wasn't really time, so we all walked to a place and had a super yummy breakfast but by the time we got home, we missed the falling asleep window.
In my defense, I did try to get her to pass out in the stroller on the way home, which was way closer to falling asleep time.
The dog is sleeping soundly on my lap, at least. She's going to be disappointed when I insist on getting up so I can change a diaper to start the whole sleep attempt over again. I feel badly about that because the dog is actively policing the cat and keeping him off me and my baby, which is helpful.

I caught her in the second cycle window and now I have a lap full of sleeping baby in the rocking chair. I think I am getting the hang of this. I assume that means the rules will change tomorrow.
