Hiccups

Hi, moms! I just wanna ask if it's normal for our los to have frequent hiccups. As in frequent, mga 3-4x a day and it usually happens aftr feeding. May scheduled check up naman kmi on monday, but i wanna know ahead of time if this is indeed normal. Nagsearch kasi ako sa net sabi normal kaya lng nagko-cause prn ng worry sakin. Thank you in advance sa mga sasagot.
