So he had first A time of 3h, followed by a 1h nap...followed by another 3h A time with a 30 min second nap? If that's the case, yes, the 2nd A time was too much. I would have cut it back to about 2.5h.
On days when he short naps, it might mean that the EAS times don't fall like they normally do, and that's just par for the course.
A thought I had was: do you think he's teething or getting sick?
