thanks for your replies, sorry, my notifications have been going funny and I only just found them!
So she's still fighting naps and I've come to a couple conclusions. We'll see what happens
got to get back to a "routine"
Lisi's got to get less snotty - poor thing can hardly breathe right now
got to start shortening the morning nap
can't let her sleep any later than 4
Less daytime sleep gave us better night time sleep (at least once, but I think yesterday was an extreme example - 45 mins nap total)
thanks for your ideas, it's good to compare notes! I know Lisi and her sleep goes in phases, some better, some worse but this does feel like it's time for a tweak. We've been on the same routine for a long time now.
