Exactly my experience and fits with my idea of how time is perceived in general. Ask a young child what they did this last week and they can likely rattle off a whole bunch of things that they've learned/experienced/discovered for the first time - a lot of 'memory milestones'. Ask your average adult and you'll often just get "same same" - no new 'memory milestones' because the week was pretty much just a repeat of a regular routine.

As for how it feels at the time. There's a lot of truth in the sayings "time flies when you're having fun" and "a watched pot never boils".

It's a paradox.
