My DD hiccuped a lot in the womb and once she was out, until around 12 weeks or so when things calmed down all round.

I think it's pretty normal with newborns and hiccups don't bother babies like they do us adults so your LO shouldn't be feeling any discomfort.

As for stopping them, I'm not sure there is much you can do. Like I said, my DD just seemed to outgrow her hiccup attacks She was demand BF too.
