If he slept for 35min from 10:50 then he woke up at 11:25, next nap was at 14:40, that's almost 4h A time!!! That's a lot. Using the same calculation his second A time was 3h, that's as well a lot...
Your A times sound ok for his age, but if he wakes up too early from a nap he can't do such long A times (even after a good nap he won't be able to). Many babies actually needs their A time shortened after a short nap, yk?
If the first nap is always short after a 2:20h A time and he wakes up happy from it then I would increase A time for 2.5h and see if it helps.
