What part of the baby am I feeling when she hiccups?

Chicago

I feel baby hiccup A LOT. I was just wondering if anyone knows what part of the babies body I'm feeling. Right now I feel the hiccups, she's on the left side of my stomach. I can feel them from the inside and I can feel then when I put my hand on it. Is it her stomach that I'm touching when I touch where the hiccups are located? It's hard to imagine how her stomach would be in this position lol but I just wanna see what everyone has to say.
