I am currently 30 weeks pregnant with my second son. During my first pregnancy, my son had hiccups at least 2-3 times a day starting at like 27 weeks and was diagnosed with silent reflux at 3 weeks old. This pregnancy I have yet to feel hiccups at all. I have heard there's a link between frequent hiccups and reflux, but not sure if it's true. It that's the case I am praying this one won't have reflux, because it is so pitiful and you basically have to just let them grow out of it.
