Just wanted to report a victory! I had been taking a break on extending naps and yesterday she was tired on the short naps, couldn't make it to her usual A time. I put her to bed and she didn't stir after 40 mins (great!), then she stirred around 11pm-midnight but we resettled her with shh pat as she doesn't normally feed that early in the night. THEN she just slept through till 6am!!

So she went 12 hours without a feed and woke happy!
This resulted in her easily having a happy 2 hour morning A time (some days she's quite tired in the morning and wants a morning nap early) and THEN she extended her nap now going on 1hr 15min (still napping) with just some HTTJ.
Overall a day for sleep victories! Hope that encourages anyone in the thick of nap extensions or early wakings.
