Is hiccups 2+ times a day normal for a 15 month old boy? he has food interolerances, is a very fussy eater but is tracking to the 5th percentile.

Hiccups: Hiccups are normal with eating too much, drinking too much or swallowing too much air. Confused since it sounds like he is a "fussy eater" but he is also growing well into the upper percentiles although i think you have your percentiles wrong. If he is only 5th percentile, then he needs to see a food allergy specialist and/or dietitian.
