yes, they go from 4 naps to 3 naps to 2 naps to 1, with longer and longer awake times, so yes the timing of the naps changes as they get older. My LO is 13 months and we've just gone through the 2-1 nap transition so our EASY is now no longer really an EASY but it's still a good routine. To give you an idea, at 10 months we were doing something like this:
E/A 7am awake, BF
8ish breakfast
S 10 nap
E/A 11.30
12 lunch
S 2.30 nap
E/A 4 awake, BF
5 supper
6.15 bath, story, BF
S 7 asleep
Now at 13 months we go something like
7.15am awake, BF
8ish breakfast
11.30 lunch
12.30 nap
3 awake
5 supper
6.30 bath, story, BF
7.15 asleep
