how does that effect night wakings?
Night waking can be cause by OT so although a LO goes to sleep easily at BT their sleep can be disturbed either with frequent NWs in the early part of the night sleep or with waking too early (and not refreshed) and having to be put back to sleep multiple times.
There are of course other possible reasons for NWs including the 4 months regression, teething (this could be the case with your LO), props, illness, growth spurts, noise or light, developmental leaps...
Looking at your EASY the difference in the last A times and CN were the things that stood out. The change in the later art of the day may or may not resolve the NWs, you'd have to try it and see how things go over a period of time (ie not just one night).
The 4 month regression is often linked to A times being too short and not increased rapidly enough for Lo to nap well, this isn't the case in your current routine as you've already increased to 2hrs, 4hrly E and getting good naps. It's all a bit of guess work.
Let us know how you get on.
