Chest pain in a child is unlikely due to a serious heart condition, but there are several other reasons why your toddler could be having chest pain.
If there was a recent injury to the bones or a muscle in and around the chest area, the pain could be a strain.
If your child has had any respiratory illness and has been coughing, the pain could also be coming from a strained chest muscle.
If chest pain is accompanied by laboured breathing, call emergency services immediately. Your child may have swallowed something that is lodged in her oesophagus and causing chest pain.
When your child complains of chest pain after a meal, the cause could be gastro oesophageal reflux disorder. With this condition, pain in the chest occurs from regurgitated stomach acid burning the oesophagus. A sore throat will sometimes accompany reflux.
In any case, you should call the doctor if there are other symptoms and if the chest pain does not subside or gets worse.
