Hindi ka mag-iisa sa concern na yan, hiccups are pretty normal sa babies and toddlers actually! A few of us have noticed our little ones do this regularly, at honestly walang dapat alalahanin most of the time, it's just their system adjusting pa lang, especially pag kumain lang or excited sila. If it happens a lot or seems to bother your baby, you can try giving sips of water or changing position, pero usually it passes on its own within a few minutes.
