Overeating
Anything which makes your stomach become larger than normal (distension) could lead to hiccups. This is mainly because the stomach is located right under the diaphragm, so any irritation or pressure on this part could be a trigger of hiccups. Thus, it is better to avoid overeating, particularly in kids. Instead, it is better to have small meals that are evenly spread during the day and control portion sizes to prevent hiccups. For example, try 3 to 5 mall meals for each 2 to 3 hours. [2]
