His routine for the day looks great! Most 7 month olds are on 2 naps and 3 hours of day sleep is pretty much the average. You could try increasing that second A time a bit and see if he takes a longer nap. Normally 1hr naps mean the LO could have handled more A time.
It looks like the NW are due to nursing becoming a prop for him. Since you're nursing every time he wakes, when he enters his light sleep, instead of transitioning back to deep sleep, he wakes fully and calls for a nursing session. Do you think you're ready to try getting him back to sleep without nursing? Also, do you have anyone (DH?) to support you through the night? The first few nights may be pretty rough, but once he's used to resettling without feeding most if not all of those wakings should disappear.
