Will you ever invite kids from your lo's childcare center/in-home/nanny/etc situation to your lo's birthday party?

I think M's daycare room is too big to invite everyone to a party. Plus, I'm not that big on events where I have to host 20+ people! I don't know what I'll do this year when she turns 3 - maybe invite a couple privately, and only if they are kids she talks about.
