We have 2 more days left of him being 3, and it has been the most enjoyable year.
Tonight (after stories and cuddles) he wanted to read in bed, so we left his light on, and when he was tired (about 40 minutes later) he got out of bed, turned off light, put on his nightlight and a CD of string quartet music, shut his door and put himself back to bed.
I'm just not sure he'll ever be this cute again.
