It can be harder to help out a child than an adult when it comes to abdominal pain or stomach aches, as they may not always be able to explain the pain they may be feeling or dealing with to its full extent.   Babies are even harder than children to find out what their issues are, due to them not being able to communicate at all what they are feeling or dealing with. It is up to the parents to advocate for their kids to the medical professionals about what may be going on, or what they have previously noticed leading up to the doctor’s appointment. Babies and toddlers react differently to pain than older children do, as a baby may become fussy, draw their legs up towards the belly, and/or start eating less.   Children’s abdominal pain can be related to an injury to the abdomen, an illness, an upset stomach, ear infection, urinary tract infection, or even strep throat. Other reasons abdominal pain can also ensue in children could be an infection passed onto them from an animal or from traveling to a foreign country.   Constipation is one of the most common reasons for abdominal pain in children. While some of the more serious issues of abdominal pain found in children include appendicitis, lead poisoning, or problems with their intestines.
