Christmas tree setup: to include two year old or not?

Hi all, now that it is December, I'm planning to set up the Christmas tree on December 13 (12 days before the 25th). My son is 2. Options are:

1. Set it up after he goes to bed, then he'll see it in the morning of the 14th

2. Include him in the setup, knowing that it'll take twice as long, there'll be screaming and crying as part of the process, probably some broken ornaments too

Thoughts or recommendations? Maybe a third option? Anyone with prior knowledge have some anecdotal tidbits to share?
