we had this problem at about months, the WU got earlier and earlier. I'm wondering if her EASY need a complete tinker? I think she might need to drop the 3rd nap, which is gonna lead to odd day lengths
The first a time seems long if she's getting up at 5 or earlier? If she's doing 3hr 15 A then maybe try and have 3 hr 30 for the first A. I foud the EW wakes started when the first and the last A times needed a tinker. She also seems to be fighting that last nap, so maybe she could handle a shorter nap and an earlier bed time, just till you can push her WU later. I found if we had too many long days in a row my lo would start getting OT and the naps and nightsleep would go wonky.
WU 5am
nap 8.30
wu 10
2nd nap 1:30
bed 5
She will have dropped the nap so hopefully will be tired enough to sleep a bit longer so then you can push for a longer day and a later getting up time. If you manage to get her to go back to sleep use this as an opportunity to get a later bed time. We had to do this several times, when he had a good night and was well rested I would push for longer day with a catnap to try and reset his body clock, but if it didn't work and he woke early I would do the above EASY . I remember having to put him to bed at 4.30 once!
I learnt tho, that now if he starts waking earlier and earlier I need to extend the A times, particularly the first and last . But you have to be careful and keep an eye out for OT because that can lead to EW too!
I hope this makes sense! I 'm trying to remember exactly what worked for us!
Thing with the EASY is it needs to be constantly monitored and tinkered with, it'll work great for a period but then some devopmental leap will happen and the ew, NW or shortened naps will start up and this is your signal to think about lengthening A times or shortening naps (with the 3 to2 and 2 to1) or both. But it has to be gradual over a couple of days or OT will confuse the issue more. Stick with it! we had a terribe time with sleep (or lack of) and the only thing that helped was BW and EASY. He's still not the best sleeper but the neither am I, so its inherited
Some mums get good sleepers, but for those that don't, EASY is a godsend!
