Eat, activity, sleep in evening ?

CariH20

So lo is 9.5 weeks and has pretty much made his own schedule. I exclusively bf and try to follow the eat, activity, sleep pattern which has worked out well. He usually wakes in the morn at either 430ish or sometimes sleeps until 7ish. After the 7ish feeding I play with him and he goes down for a nap about 45 minutes after he wakes.  We follow the same routine after every feeding and he stays awake around an hour give or take and then naps a couple of hours give or take. So my question is about his feeding that is around 530pm to 630 range. He will usually be awake like usual after the feed but will want to nap up until his 830 pm to 930 pm range feed and then it is bedtime. So, do I wake him early from his last nap and maybe do some type of routine with him so that he is awake a bit before his last feed Andy bedtime? I'm afraid he will be cranky if we do that but then again it will help him separate naptime from bedtime ?
