Just read all your gorgeous messages thank you.
As for routine: did the nnd four days ago but he hasn't slept long enough yet to get us back to another. Nights have been shorter since the nnd than they were before: 10hr30, 9hr, 10hr30, 10hr20. Prior to nnd they were: 10hr35, 10hr55, 10hr10, 11hr30.
Since the nnd, I've also pushed him to a 7.30 pd at bt and he's asleep in 10-15mins.
So nights have shortened consistently since later bt and one nnd.
Should I just stay with what I've got?
