Mine gets hiccups multiple times a day too! I was just lying in bed last night worrying a little about him having them too much. But I do know it's a normal thing...I have a Doctors appt. tomorrow and I'll ask and let you know what he says.
MIne does at least once a day. Makes me smile.
I don't think my baby hiccups at all. He's always moving and kicking. Not sure what a hiccup would feel like. Sometimes it looks and feels like he's sucking his thumb - maybe this is the hiccups?
