i am 32 weeks this week, and bubs regulary gets hiccups, up to twice a day for maybe as long as 10-15 minutes.

i have never heard about reporting excessive hiccups before, but my first bub never really got them much at all. i have only ever heard that hiccups are healthy lung practice for them, but you cannot always believe what you are told or hear.

if you are concerned i would just ask your carer.
