question: My 2 1/2 yr old as always had a big belly. At her 2 year check up the pediatrician questioned why it so big (like we would know), but she never seemed to concerned. My 2 yr old lately has been complaining of her tummy hurting and last night it felt really hard. Usually simple things help, like giving her a snack or something then she will say it doesn t hurt. Could it be more serious or just growth and changes in eating habits?
