Lol! Did you manage to get him into the cot after that?
It could still be developmental too, I suppose

- he's still at that age where short naps are quite common. We started to get consistently better naps around 5 months from memory.
But if he normally manages 2hrs first A easily, I would persist for a few days trying 2hr10 just for the first A - you might need a little bit of gentle distraction to keep him going. If that nap gets shorter rather than longer, you'll know it's pushing him too far.
If your first nap is still only an hour, I would try a slightly shorter next A time

Something to bear in mind too is that some babies do just like different A times throughout the day - mine would have a short first A, longest middle A, and A to bed was somewhere in between!
