Ya Jec at two I would be inclined to think this is sleep resistance and has nothing to do with not needing sleep and everything to do with them reaching that stage when thy realize things occur while they sleep and they do not want to miss it ...

I had one that age do the same thing for a few weeks and the expectation to rest quietly consistently sent each day he is back to sleeping well again
