Apologies for the slow reply, somehow I didn’t get a notification. You are more than welcome to share my email with your friend. I found a partner, but I know people often have more than one.
As for the shared room, I was just going to update that post—thinking of bedtime starting much earlier, working in roughhousing/giggles/connection games throughout the evening, and just assuming that it is going to take an hour longer than I’ve planned has helped A LOT just over the last few days. And my youngest still naps, so I have also been trying to give her good listening time when she gets upset at naptime, in the hopes that it will clear out some of those bad feelings before bedtime when her brother is in the room.
Best of luck!
