Hugs for the nw's and ew. Here's some info on ew's
Early Morning Wakings. Sometimes Los just stop ew on their own but usually it means a routine change is needed.
Regarding your Los routine, you might want to push out morning nap so that its occurring 3.5 hrs after wu. I would gradually increase the morning A by 10-15 min increments and see how he does. The mid day A is alright (perhaps a bit long).
Do you have black out blinds, white noise on, etc? In the morning our bodies are progamed to sleep more lightly and thus external stimuli can wake us. So try to block out the stimulation as best as you can.
With regards to night feeds, I think it depends on whether or not he's hungry at night. If he's hungry then you need to increase his DT calories so that he eats enough throughout the day and he doesn't need a night feed. But in the interim he will need a nf. If feeding at night is just habit, then here's some good info on ways to wean the nf.
