Well last night went better, so I guess a later capped nap helped. He cried out at 4.05 and 4.40 and possibly murmured at 5ish but otherwise slept til 6.15
So I'll try the same today. I wonder if I need to cap a bit more still, but I'll see how today / tonight goes first.
And yes, I find the whole LSN thing hard work sometimes. J seems so sensitive to even a little bit too much day sleep at times, and then will have phases where it doesn't matter so much. I'll be glad when the nap is gone tbh, and it's not a factor any more. Not long now I reckon....
