I had this similar problem with my son. He was always going to the bathroom and still having accidents. I thought it was just a boy thing until his preschool teacher told me to take him to the doctor to check for Type I Diabetes. I went that day and a blood test ruled out diabetes. My pediatrician referred me to a urologist and he was diagnosed with overactive bladder. He takes prescription medication everyday and it has really helped. I didn't realize until later how the accidents affected his self esteem. He is eight years old, still sees the urologist yearly, still takes the meds, and still wears Goodnites at night. I urge you to call your pediatrician today!
