Part of the BW way to do things is just to go with the flow--it's not a rigid schedule. If your lo is going to take 45 min naps, then that's the way it's gonna happen. We'd all like our lo's to take 1-2 hour naps, but lemme tell ya, it's not real easy to achieve some of the time, that's for sure!
And yeah, when it comes to the 4 month transition to being awake for 2 hours, it's NOT easy (pun intended). You have to go with the flow, or you lose it. It is a developmental stage. It will pass with or without a real BW schedule. It may look like EASAES for awhile. That's the beauty of the system.
What you want to continue to do though (which is at the heart of the BW way) no matter what, is avoid props as much as you can. After 6 months, prop habits become increasingly harder to change.
You guys are doing great, venting is real good during this time! I just got through the 45 min nap period...and there is an end to it. I didn't think there was, but there is.
