Feeling hiccups in my butt!

My baby gets hiccups a lot! At least 5 times a day and that's just the ones I actually notice. I always feel them really low in my belly but the last two days I have literally felt them in my butt! I don't even know how to explain it. But I know they are hiccups bc it's the same rhythmic pulses that I felt in my tummy. Anyone else feeling them that low? Is this normal?
