Baby shower for third baby??

Allison • DD 🖤 DS 🖤 DD due Dec 🖤

I’m pregnant with my third. I had baby showers (family insisted) with the last two pregnancies. I have a feeling they’ll want to throw one again for this baby, but I don’t really want a whole shower. However, I’d like the family to be able to have a gathering to celebrate. What did you do for your third? I’ve heard of “sprinkles”, but I’m not sure what they usually entail.
