Normal for baby to hiccup 2-3 a day in the womb?

I noticed i feel my baby (29 weeks 2 days) hiccups like 2 or 3 times a day

and my husband just told me it’s because I crave and eat a lot of spicy and sour foods

is it normal or should I be worried?

I have a glucose and anemia test tomorrow morning should I ask about that?

should I change my diet and ignore my cravings?
