I think it's a case of planning ahead and realising you don't always have to move E ahead too far - some points in the day EASAEAS will be the thing to do, but at others (ESP if very short naps) then EASAS may be better and you can actually delay E a bit. It's a bit complicated but assuming 45 min naps, an A time of 1h20, maybe an hour or so after a short nap:
WU & E 7am (feed due 10am, nap due 8.20)
A
S 8.20-9.05 (next nap due 10.05 - so bring next feed early to avoid clash)
A
E 9.45 (feed due 12.45)
(A)
S 10.05-10.50 (nap due 11.50)
A
S 11.50 - feed on waking etc etc
Does that kind of make sense?
