Welcome, DeeDee! My name's Cece.
This is a wonderful, supportive place to learn and share.
I agree with everyone's responses. For some reason, it's really gassy and noisy at first, but give it some time, and it will quiet down a lot. The only time mine gets a little chatty is first thing in the morning when I have a cup of coffee or breakfast on an empty stomach, which is okay, since I'm at home 99% of the time. If I'm visiting family or am at work when it happens, I'll casually press my right forearm against it, which completely muffles the sound. Hey, at least we can muffle it and don't smell up a room, unlike people without ostomies!
Hang in there, it will get better!
