Baby has hiccups a lot... Normal?

I'm 31 weeks today and I have noticed my bubba has had the hiccups 5 times today, is this normal? Does anyone else's baby have the hiccups this much? I remember having them with my first son but can't remember how many times a day he had them. I was looking on Google and it saying something about the cord around baby's neck if baby has hiccups more than twice a day.
