Why does your uncircumcised baby leak urine when changing diaper?

Babies need diaper changes because they have not learned how to control when they urinate. Instead of urinating a few times a day, babies tend to urinate more frequently in small amounts. Also for boys a few drops of urine may collect in the tip of the foreskin. These few drops of urine leak out as you wipe the penis during a diaper change. Always make sure to keep baby's uncircumcised penis extra clean.
