Most children who complain about having tummy aches will say it everyday at the same time. For some children it is at night before bed and for others it is every morning before school. Tummy aches could be because of illness but if not then it is caused by anxiety. The enteric nervous system is located in the stomach. When kids feel nervous or anxious, their body may relay these feelings to the enteric nervous system causing this area to feel uncomfortable.
