Has anyone found a great way to keep their toddler quiet during church?

LO is 2.5 and we've been slacking with taking him to mass. The last time we tried was about a month ago and he was so loud (in a happy way, reading his books out loud, saying hi to everyone, etc. but still disruptive)!

I think most people are okay with it, more or less, because he's just babbling and being cute, albeit loudly... But I want him to sit quietly lol. I wish our parish had a children's program, but they don't

Any suggestions for activities or strategies to keep a 2.5 year old quiet for an hour? It's really important to DH that we all go to church, but it's really stressful for me to have LO bouncing around making a ton of noise.
