It’s working! I feel like SUCH a moron for not doing this before, but making sure Jack’s room is super-dark seems to have fixed our nap problem. (I am totally jinxing myself right now, I’m sure.) After a few days of hanging the comforter over the curtain rod, I bought a cheap blackout shade, cut it to fit the window, and stuck it to the top of the window frame. I still close the curtains over the shade and tape the edges down, and it gets nearly as dark as when I used the comforter, with the added bonus of not having the extra weight try to pull the curtain rod down.
Here’s what you want to know:
Jack has napped (!) in his crib (!!) for EIGHT days in a row (!!!), and EVERY nap has been between 90 minutes and two hours long (!!!!). He has slept through the night, nine to ten-plus hours, for every one of those nights except one.
I know this won’t last forever (growth spurt, sleep regression, his two-year molars – have I mentioned that he already has all of his teeth except for those four in the very back? He has so many teeth! – something will happen to disrupt sleep or naps), but I am going to enjoy it for as long as I can.
